Determine if an old used Jeep for sale is still in good condition by inspecting its engine for cracks in the exhaust manifold and looking for any odd sounds or excretions, proper wheel alignment and a firm gearshift. Other factors to check include the state of the interior and the top covering.
The state of the Jeep's engine directly affects its ability to function and any potential post-purchase costs. Begin the inspection by turning on the vehicle to make sure that it runs, then let it idle for a few minutes. Listen to the sounds of the engine, as any pops, sputters or sharp noises may indicate deeper issues. Check the engine from the inside and beneath to look for any leaks, which may not be apparent at first. Let the Jeep run, and shift its gears to test all the functions.
Once you determine that the engine is sound, drive the Jeep a short distance to test the brakes, power steering and wheel alignment. Inspect the condition of the heating and cooling systems along with the lights and dashboard signals. Examine the top of the Jeep to see if it has any rips or holes and to ensure that the zipper opens and closes smoothly.
