Choosing a used car , going to analyze the most appropriate model for our particular case.
Among the many cases that may arise , the cover is a need or a whim, if a priori both situations may be similar , in practice are radically different.
In the first case the variety of models to suit the need , can make us more demanding when asking minimum requirements , in the second case we may have to sacrifice certain sections , provided the minimum considered necessary are covered .
CHASSIS
The chassis section is very comprehensive and the treatment it receives is not equal to freestanding models with independent chassis and chassis , there are few cars with separate chassis, although it is still common in all terrain vehicles .
The condition of the chassis is very important, in many cases more than the state of the mechanism itself, since its replacement is more laborious and expensive in many cases , just because of the labor required , and the worst finish is obtained.
The status of the chassis will be seen from two perspectives :
A) Structural capacity that maintains the design values for stiffness , performance and security of both active and passive.
B ) Status of corrosion protection to prevent future degradation of values of design and manufacturing.
Ideally suited to safeguard the status of the case, is that the vehicle in question has not been used in harsh conditions :
Moist , salty environments
Poor attention to the protection provided by the paint
Repairs performed poorly
Strokes may have affected its structure
Damage to the underside hardly appreciable
Vehicle from flooding or waterlogging
Some of these conditions can be exclusive, but not necessarily be so in many cases the result of a repair can not affect the overall structure , nor the intensive use of a vehicle in wet environment is limited due to their choice, but a more thorough analysis .
How to see if a repair has been made , and the valuation of the same .
If the car has repainted , will have to see that reason has led the intervention, which elements were damaged , why and how they have managed .
Damage to elements of the chassis are basically UNACCEPTABLE , unless these have been repaired properly and no damage to make us reject appreciate.
The damage in the beams affects stiffness of the car and never returns all values to their initial levels chassis , and could only be accepted with reservations , when the type of car and the use to which it entrusts justify its election to the multitude of supply of resale ( classic car exclusively for cruising).
How to observe them and to be ?
The self-supporting chassis rigidity based on the diversity of sheet metal parts that make up the body and especially on the elements that run through the car from front to back . The different thickness of the plates and their folded form and give the necessary rigidity to the chassis stiffness invested in maintaining the suspension at its optimum operating point and also absorb ( deformed ) upon impact preventing runs on the occupants .
The deformation of the parties supporting the chassis rigidity imply that when these to their original levels are returned to the fold resistance have been severely depleted , so its stiffness changes completely, although their aesthetic measures or even the appearance this this the right look .
Inspect the stringers , identifying welds serves to first know if there has been repair and secondly, to see how it has done, is determining whether there has been repair and in this case ... if this is appropriate.
Soldiers use putty is the best clue to whether there has been a significant intervention , and subsequent testing of the vehicle with the chirps that they will appreciate in strong support will be very useful for assessing the status of the chassis at this point elements.
Flag that any repair is always worse than a job done unless it makes complete replacement part and comes with protection and manufactures only the absence of painting, parts replacement , correct assembly and welding is indispensable condition for acquiring the vehicle, and if the job is well done , it should not be detected in a visual inspection , if a botched repair, shall be inadmissible ... because they know the state in which said frame absorb a blow for which it is designed.
Exterior finish
Once we have ruled that the repairs have affected the beams that make up the chassis, we focus on the rest of the car .
The doors should not close the hard way or present mismatches, verify proper closure and hinges are necessary to get an idea of whether interventions have been a very common trick is to check the rubber seal with chalk , closing the door record shall be the place that really makes the closure , thus ruling out bad seat areas that aside from being able to point to a bad repair we undoubtedly generate noise nuisance or even water inlets .
The flaps and bonnet must be examined to check deformations , poorly painted areas oxide and the like , repairs only tend to do well facing the outside, passing a magnet of low intensity and see the presence of filler is not very logical , I accept input so putty repairs existence lay it down safely in an array, you have to be interested in their level of repair .
The rust on a repair is a symptom of a painted poorly done and insufficient protection to the plate , rust extends inside the sheet and presence abroad may be just the tip of the iceberg , to be seen as the fruit of repair or bad condition.
Scratch the paint if they are not deep not eliminate the protective layer that receives the metal before painting , but painting this protection is lost , no more mission to return the outward appearance , but is not important for the function protective intended.
The presence of rust in both the exterior and the low (very prone to these defects ), or the area of the battery that usually suffer the ravages of poor handling , should not exist and if they submit returning delete the original qualities to the plate and preventing its extension. Rust in these areas can move forward and end the resilience of the chassis in key areas.
There analyzing scratches and minor knocks that may affect or alter the surface of the painting and its external resistor .
Presence of hidden mud
The mud is the enemy that we will flooded car, which in the lift cars are known as " flood " your weight may go up by more than 100 kilos of a similar car and the worst is the smell given off when the weather turns wet , the worst is that accumulate moisture and rust the frame just did not appreciate where ... wary of new cars with very few actual miles, and good appearance , detection is complicated and only an exam can betray them very thoroughly . Its origin as the area can be telltale signs of such vehicles.
The interior trim are sneaks interventions doors and panels is difficult for these do not show the effects of removal, a poor job of retrofitting to generate apart from most noise , accidental water by licking moons windows into car panels for door trim .
PAINT
The paintings of cars besides providing an aesthetic appearance help keep the sheet protected from the elements .
Lately there has been widespread acquire vehicles with metallic paint and these have earned fame resistant better than the so-called solid colors ( devoid of metal ) the reason is not so much in whether or not metallised time, if not in the type of paint used .
Acrylic paint is much more resistant to sun and has an acceptably good condition over time, enamels gliceroftálicos employees well into the 70's aged badly and are responsible for the bad reputation of solid paints ( red in particular) the incorporation of metallic shades , extended the use of acrylic enamels in their tones , now practically the generality of vehicles have acrylic nail type and onwards will not be difficult to find these car models with paint so punished , not no reason to despise a car not wearing metallic tone if this is a recent bill for fear of a bad aging.
The white color is still the least punished by solar radiation but the color is one of the most personal issues in choosing a car.
Good appearance must be an element rating , but more for a lower price than to rule a purchase, if the car has been repainted even scratches will be much better to keep wearing protective veneer factory that enter their aesthetically repair unless we deem necessary .
Inspection of low
These should be inspected especially in vehicles that are expected to have been used in field damage apart from them may affect the stiffness of non-visible areas or the loss of protection against stones bearing chassis .
Inspection of Glass and mirrors
Check for cracked especially in lighthouses can spare you trouble later , just as the optics must be submitted with good looking , as this affects the luminosity that are capable of projecting .
The windshield glass , it is important not present rajas , as these tend to grow with temperature, and if you have the effects of a stone, these have been repaired without being future stars that derive rajas.
Adjusting doors, bonnet , wings , bumpers, etc.
Correct adjustment of doors bonnet and wings is a symptom of the lack of repairs or the proper execution thereof. The bumpers and anchors give us an idea of using heat and put the driver at his care.
Review of handles , windows and locks
The key areas are very sensitive to the introduction of grated keys, remote controls have made these areas remain notification disputing the bad treatment of the driver but the smooth operation of handles and locks, as well as ease and smoothness when the door handle will give us an idea if we can expect noise and squeal gears if not at present in a short space of time.
Tires and suspension
The correct tire tread wear and in some cases the date of manufacture can give us an idea of the miles , especially in cars that are presented very new and few years.
If the spare tire is of a different brand to the other will have to estimate when these have been replaced and if mileage is logical , wheels of different brands or drawing should not be accepted on the same axis , the state of the drawing and the depth same lets us know when we have to rush and change the money involved.
The tire wear is the type of use and it is difficult to know exactly when a set of tires wears items that will give us a more approximate idea of the approximate actual mileage , but we must not fail to inspect if your tires to wear or cracking requires replacement
The cushions have a highly variable state of one model to another , it is difficult to know if they are at the end of life or are still usable when there are models out chain , many drivers and replace , so elo fact sink and see that oscillation damping in one cycle (ie the car goes up and stays not bounce ) is highly debatable , however the test is to see if the misuse of curbs or side stroke damage generated one. We will estimate if both wheels is , are damped as quickly , otherwise serious symptom of wear or damage one , forcing us to replace at least one of the two axis.
The dynamic test seriará us to go through the broken sign , verify if the oscillations of the body tend to incriminate more on one side than another symptom of a cushion in poor condition, it can lead to a more pronounced inspection of suspension on that side in search of a hit in the arms that hold the wheel or tire damage to itself.
In removable roof car (off road ) checking handling anchors helps us to know if there have been improperly or carelessly , the damage from these can reach the protective layer of paint.
The interior condition of the car should be ok , trims that are removed are never equally and as well as consideration of lights and auxiliary elements tweaking expensive one that sometimes is never done , check seat anchorages , dashboard, bags doors and other necessary and can give an idea of the use ( an elaborate seat is a symptom of many miles ) as buying a used car should not be hasty to compare with similar models can serve experience to decide on these chapters in the car you do not really generate the appropriate interest.
Belt anchorages and braiding them makes them useful only in a coup , if in case of impact these have not been replaced will have lost its mission, the aspect of the belt should be the standard and interlaced fibers form a grid with a sharp angle to the length thereof , the reaction when pulled should operate.
Heating fans should be quiet and not create noise , it's good to put it on medium speed , not the maximum , because if you have gaps accused him precisely in this area that is the usual work , a widespread use of it which generate have to be changes .. and lack of accessibility in many cases will make it more expensive to repair other hand more .
formulisms
Finally in the case of the chassis should not be underestimated as routine checks verify that the chassis number match the technical information in this appears the date of manufacture , which can be helpful to know when you are registered and whether there delay between enrollment and manufacturing reasons we estimate that it has led to ( possibly test car or exposure or has it repaired by a blow to the transport.
