Im not too familiar with these cars, Im more a muscle car old school. But hey what can I say.....a good way to learn

Also I was wondering if anyone could give me advice? There is a 02 wrx I want to buy, but it has 175 xxx km, is that still ok if hes asking 10 500 canadian? I heard the 02 had weak trannies? What are some things to look for when purchasing these types of cars?
