I've had my 2007 M6 for about 2 weeks now and am totally blown away with how much fun it is to drive. My last vehicle was a 2007 Porsche 997tt, RIP wrapped it around a light pole. I never thought I would be able to replace the tt, but the M6 is quickly making me forget all about it. Already took out the charcoal filters, whats the next logical step in the mods process?
