Ride, comfort and safety are also important aspects to consider in  purchasing your used vehicle. Visually inspect car to see if it sitting level in the front and back. If car is lower in front or back it is very possible the springs could be worn. The first components to check are shock absorbers and springs. An easy test for worn front and rear shocks is to bounce the front and back of vehicle. Do not push on the center of the hood or trunk with your body weight or you could dent either costing you money before you even test drive it.  The vehicle should not bounce more then one time, if so replacement of the shocks and or struts could be needed. In the event that the car bounces easily and multiple times, visually inspect the shocks or struts.  If oil or wetness is visible, this is another indication of worn components, which will require replacement to maintain the safety and comfort of the vehicle.

On cars equipped with air ride suspension; it is even more critical to inspect height and level of car, because air ride suspension components can be very involved and very costly to repair.

Now take a look at the tires. Are the outer edges worn? This usually indicates a front end that is out of alignment and or has worn front-end components. Deduct money for this. Do not buy a car from anyone who would do an alignment on worn tires.

Now it is time to test-drive the vehicle. When test driving check for ride comfort and stability. The vehicle should not be bouncy and/or feel unstable. Remember bouncing is an indication of worn shocks or struts. When cornering, the vehicle should not lean excessively.

A vehicle that pulls to the left or right while being driven could indicate a front end that is out of alignment or tires with uneven pressure. Does the car shimmy or vibrate? When the front tires are out of balance, the front of the vehicle or the steering wheel will shake, especially at or approaching highway speed.. Usually when a front end has been maintained properly, the front tires will be worn evenly across the tread. The vehicle will feel  very tight and responsive. Be very careful when addressing this area, because it is a very important part of the your state's safety inspection.
