6k is fair in my opinion...you have 25k miles more than I do..mine is 4 and 50..and I paid 4300 plus 400 on interest ..24 months$6118, no tax. $600 down $300 per month for 18 months (interest free). I was really hating this price until I saw the price of a new M6 . 128K. $6K seemed like chump change after seeing that. lol.
