I have a hard question to ask, worth a shot though - Subaru Owners

This is an 08 WRX with about 140k miles. No accidents, no damage reports and 3 previous owners according to CARFAX. I drove it and it pulled fine, did about 100mph on the interstate lol and it felt fine. Has boost gauge, invidia n1 single exhaust, Cobb down pipe and k&n air filter. I checked this car just about the best way I could. The asking price is $10,250 before fees. Would you buy it? How come?
