Just tried to do an all out search for an slk, c class, srt6 and apparently xmas is affecting used car pricing, lol. I have been thinking that if I were to get rid of my SRT6 then it would be for a SL55 or maybe an XLRV, but alas that is not to be for awhile. Good luck with everything John. Maybe you can put a rear turbo on it sometime when its available.
