Pre Purchase Inspection Points Before Buying A Used Car

by | Jun 21, 2014 | Car Tips

According to used car experts like NadaGuides.com, an inspection is an essential step in the purchase of a used vehicle. This process should be performed by a mechanic of the buyer’s choosing – preferably someone the buyer already has a trusting relationship with. The inspection may cost a buyer a bit of money – the average inspection typically goes for around $100 – but the peace of mind it offers can be priceless.

If you are in the market for a used vehicle, check out the pre-purchase inspection points offered by NadaGuides.com and other experts you should cover before you take that vehicle home as your own.

Engine Inspection

The engine inspection may be the most important component of your pre-purchase inspection. NadaGuides.com suggests potential owners may be able to check out more of a car’s engine features than they think, even if they are not mechanically inclined. However, a thorough inspection should probably be left to the professionals. Some of the points to include in an engine inspection are:

Tire Inspection

Tires can be expensive to replace, so check out the tires on a used vehicle before purchasing as well. While worn tires may not be a make-or-break issue in the purchase of a car, price should be adjusted accordingly. According to NadaGuides.com, a tire inspection should include the following:

  • Tread on tires should be at least 1/16 of an inch or more
  • Tires should be from a reputable manufacturer, such as Michelin, Good Year or Bridgestone
  • Unequal wear on the treads could signal problems with shocks or misalignment
  • All tires should be the same size and from the same manufacturer
  • Tires do not have any cuts or cracks on the surface

  • Automatic transmission engages right away, without slipping
  • Neither manual nor automatic transmission grinds in reverse

Brake Inspection

  • Vehicle does not pull to one side when brakes are engaged

  • Brakes to not squeal or make grinding noises when engaged

Miscellaneous Inspection

  • Owner’s manual should be stored in the glove compartment of the vehicle
  • Headliner (fabric on interior roof of car) should be clean and free of tears
  • Service and repair records are provided to show vehicle’s history
