I have been looking at the G35 coupe for a couple of months. Very nice car.
I also looked at the Acura TL. Both of those cars when to second and third after I drove the Lexus IS350 last week.
Bottom line is that you can’t go wrong with the G35. Rear wheel drive, about 280 hp with an auto, even more with the stick. Design is a bit aged, but it holds it own against the TL, IS, BMW 330 etc.
