want to get a GTI/GOLF, need opinions

I got a 2006 rsx-s that i leased, im trying to find someone to take over my lease...The reason im doing this is because i dont feel like paying for the payments every month and need the money for college.. One of my friends just acquired a 2001/2002 VW 4 door GOLF. He got it from a european car mag editor that used it for "how to's" and drove it from state to state for his photoshoots...The car has many performance parts but i dunt know the exact specs...it has an upgraded turbo,full suspension, bigger brakes and other goodies...the guy had gutted the whole car out and put in all upgraded parts...its blue and my friend is planning on putting a spoiler and an R32 body kit on it+ rims...here's the bad part...it has 150k miles....the upgrades dont have many miles on them though, it has had an oil change every 3k miles with synthetic...all the stupid typical VW problems such an engine coils and clutch have been fixed...He is goin to sell me the car in a few months, just in time for the summer...He supposedly said he beat a older ZO6 from a roll, so im sure that its very fast...let me know how much you guys think this car is worth and what i should offer him----i also would like to know, on top of the money im spending on the car, how much money am i gonna need for repairs, and what should i fix b4 problems arise on this high mileage vehicle?
