I got this 07 M6 base almost two years ago for 16k, needed a p/s hose, front tires and a good cleaning. I really like it and have done a HPDE day also, but with the C7's and the mid engines coming out, my strategy is to wait and see. Ls2 &3 are to close in HP, IF I make a change I would go Z06. Bottom line is you only live once, so if a GS is a must have sell what you have and look for your dream car!
