I have had my M5 for sale for about a month now and I have had very little interest. The car has 20K on a rebuilt engine and lots of aftermarket performance parts. I have had the car for a little over a year, and now that I am away at school I can't afford to keep it. Over the last year I have not added any more performance parts, I have just done maintence like new Ferrari front rotors, new starter, and new stock plug wires ect ect. I am asking 14Kobo. A dealer offered to put it for sale at 11K and give me 9K. I would love to get 12K for the car. Is this unreasonable? Any information would be great.
