Good news is not much. I can only from experience so its as follows:
Go for an Auto
Check auto gearbox goes up and down smoothly (check for judders at low rpm)
Complete Service history is an absolute must. If not perfect its evidence that previous owners have not understood or failed to appreciate the car and probably means it wasnt loved and cherished. No amount of work will get this back.
Check for pulling when braking, bad for rear callipers.
