Meant for the non-mechanically inclined reader, the checklist below highlights some potential problem areas to look out for in the limited time you have to examine a used car. Remember to inspect the car in broad daylight and not in the evening or at the night. A tip from the pros: Putting a Piece of cardboard under the engine after the test drive will help show fluid leaks. By the time, you have gone through the checklist, you should know the condition of the car at least as well as the owner does.

Great list, though not entirely practical due to time constraints and other miscellaneous factors.
However, a few other tips would be exhaust smoke (no smoke?, blue smoke?, white/black smoke?)
Also, body panel wave patterns and gaps between them are good indication of repair works.
