I've seen lots of threads on buying used scoobys, High Mileage vs Low Mileage, high use vs low use etc etc.

What are the right questions to ask when buying a used WRX. What should I look for, listen for? Clutch judder and piston slap have been the most prominatly suggested so far but not entirely sure what else to ask about.

Thanks in advance.
