There is no way to compare prices on a car with under 10k miles/14 years old. IMHO, I'd hope for $20K and pay up to $30k. It would be hard to justify more than 60-70% of orig. price- the car is used and is not THAT rare. I'd be concerned about the driveability after being stored that long. Mine doesn't like to sit for more than a week... How munch should I pay for a U.S.version E28 M5 with less than 10,000.miles it is from a private collection but owner new financial order has this car to let it go
