l am interested in buying a Subaru Impreza WRX but was wondering how long would the turbo charger last? How long would the motor last with routine maintenance?

200 thousand miles with frequent oil changes.

They're good engines. Let the car idle after long periods of driving to cycle oil through the hot turbo. It will last longer.

totally depends. Many have been beaten to death through their lives, and wont last too long, while many have been driven normally and maintained well, and will last you for a long, long time.

really, REALLY depends on the previous owners. Young people=beat it to death. Old people=good

other then a honda a subaru can last 4ever. but it also depends on what after market parts you put on it like intake and blow off valve. l just got a 2007 wrx and its the best car ever.the biggest problem right now is the tranny cuz they have more torque then hp. a lot of people are put'n ST l trannys on there wrx try going to clubwrx.net or wrxfourm.com You really should get one
