How do you compress a transmission, or air conditioner or onboard computer/ In the old days, a compression test could pretty much tell the issues.As to rental cars, rental companies have been recently cited over and over for not incorporating safety recalls, and they likely scrimp on maintenance. I'd pass on a used rental car, even though most probably will last for many years.
True that, so I'll put my faith in a good compression test first.
Nowdays, you can't even pull the plugs to test compression with removing half the stuff covering the engine. The readouts from the computer are about all you have, and they don't tell you if a car was severely abused. They do have memory devices that record the last XX hours of operation, but only a dealer can access them.
