I have both an E92 M3 and a G37s Coupe. NO comparison whatsoever. The M3 is better in every single minute detail, facet, and way. The fit and finish of the interior on the M is far superior and the acceleration is night and day. I can't even stand to drive the G37s anymore. When I do drive the Infiniti I can't stop comparing it to how bad it is compared to my old E92 335i let alone my brand spankin new 2011 M3!! I can't wait to get rid of that thing and get something else when the lease is up. Actually this G37s convinced me that I will not buy Infiniti again!
