If you go and see the car and it looks good on the pictures but they all do, check that all the warning lights actually illuminate when you switch on, you need to see them all, no blank spots, important!!! Then switch on allow all sounds to stop and start the engine. Check that oil pressure is at 5 bar and is charging OK at around 12/13 volts. If all looks OK, take it for a drive, in auto's when warm, ram your foot to the floor and let the revs come right up to check that you have no issues (watch your mirror). Check discs for wear or ridges, they should be drilled and vented. Check handbrake holds car on incline in neutral. If those points and the normal stuff look good, then you probably have a decent car. MUST check history and have full service record, look carefully at the stamps! Check engine bay for any signs of bodging, it should be clean and tidy. If you can get to it check the main cambelt for tightness.
