FWIW, yea the vf52 is a great turbo. I'm still like'in mine 13 month's later.
I also agree 15k is high. Tell them the car is mod'ed, what were the oem parts that bad, everyone knows, nobody wants a car with all those mod's on it. It must have been driven hard. I'm sure that what they did to the guy that traded it in...
And now they want top dollar for it...
