650 vs M6 Reliability
I currently drive 650 XDrive GC. Almost 2 years no issues except some oil consumption 1-2 quarts every 4-5K miles. I am wondering if I should buy it after the lease or try to get into an M6. How about the longevity of the regular V8 vs the M version? Any input highly appreciated
