Agree with Alain, naturally. $5k is on the real high end of what you would get for it IMO, I would say closer to 4k. I sold my T5M for $4500 but that included two sets of wheels, both with new tires and a shit ton of maintenance plus performance upgrades. Given that the car is now in Cali with a larger market, he could sell the wheels/adapters for a grand if he wanted to.
It's unfortunate, but x70s aren't worth what they were a year ago. 850s aren't worth shit. I had to damn near give away my 99 R and my 98 GLT (which had a brand new head and all preventative maintenance done on it). And it will take a while to sell. Took me a month or so to sell the S70.
And Matt's right too, just from looking on CL, the average P2R now with higher mileage is selling for 6-8k. Joe Schmoe looking on CL is going to see your add side-by-side and the P2R is going to look like a better deal.
