My past 2 cars have been a 91 camry and accord, and am looking into purchasing a 2002 Subaru Impreza 2.5 ts stick, it has 168,000 miles and is being sold for $2500. The car history shows that it's only had 2 owners and it's timing belt was replaced at 100,000 miles, but no other major maintenance was done. I'm aware of the head gasket problems with these engines and am not too sure how common this problems occurs with these cars at this mileage. I'm assuming the clutch is gonna need to be replaced at some point too, any advice or things I should look out for when I check out the car? Or is it not worth the hassle?
