Musty smell or dampness in trunk may indicate collision damage. Tires Wear should be even on each tire and among the set. Tires must be the same size. Wear should be consistent with odometer mileage. Insist on a spare, jack, and lug wrench.
Suspension Push down and release each corner of car.
If it bounces more than once, car may need struts or shocks. Push and pull on each wheel from beside the car. If wheel moves in or out, bearings or CV joints may be in bad condition. Remember that uneven tire wear may indicate suspension problems. If car has new tires, be extra careful in checking suspension.
