Make sure that on a hot day and with the engine idling normal, that the temperature guage doesn't move up even with the AC on. This would be a sign on a clogged radiator from head gasket leaking oil into coolant.

Test all of the electrical switches, make sure that with ignition on and engine on all of the indicator bulbs (idiot lights) are lit.

Make sure it downshifts when flooring the accelerator when climbing a hill at 45MPH or so.
