Depends on many things - condition, etc. PM me, and I'll tell you how mucn I paid for my 2003 with 24,000 miles last April. My issues with an 8 year old car that's pretty much just sat is - gaskets, seals, etc. They must be dried out, etc. I don't think it's a good idea for cars to sit. I would go over that car VERY carefully. Remember, you're going to have to drop close to $2K right away for new PS2s to replace those old run-flats, so factor that in your cost. I had to do that with mine.
I think that price is a little high, but in the ballpark.
