Hey, ive always wanted a Wrx, but im a volvo guy so dont know a whole lot about them. Ive found a 02 wrx with 43k im intrested in. Its pretty beat up, but everything has its price. The paint on the front and rear bumper is cracked up, along with dents all over it. Something on the car whines on the car like a supercharger above 20mph. Also sounds like the rear diff. is whinning a bit. How much does this stuff cost to fix? Also the front tires are shot on it. Stock apart from a bov/turbo timer. The owner said 'it needs a tune up, bov is letting air out early, it needs to be ajusted.' He also said 'its needs a new o2 sensor thats why the check engine is on.' How much is the 'supercharged noise' and the possible 'grinding diff'' going to cost to be taken care of? Also it has clutch jitter, is that a call back on the car? finally, what is something like this worth!? It has a flip up screen and some 400 ebay wheels on it also. Thanks in Advance!
