I moved from an '06 g35c.

Interior: the 37 is hands down amazing. Blows the 35 away in ALL respects.

Exterior: 35's styling was very nice, seems that did improve the 37 in some minor respects, but not enough for me to say its a SOLID improvement.

Drive: seemed to me that the 35's drive was smoother, but that could be because I went from non sport to sport.

Overall, the I loved the upgrade, if only due to the interior.

Good luck!

 

I'm on my 3rd G coupe since first getting an 04 6MT 3 years ago. Once my lease was up on my 06 coupe back in September, I was not impressed by the G37 as well. Leaning more towards the 335, and although I really liked the A5, many ppl I know that have/had Audis experienced MANY problems with them. Plus not sure I could have waited it out until May for it to come out.

Like everyone here says, just go test drive them back to back. Although my neck still breaks when I see a 335 coupe (not many in Detroit), overall I just felt better in the G37. Not to mention I saved about $5k in price.

Just go with your gut. That 0.4 sec difference in 0-60 times is neglible in everyday living.

 

I came from and 05 G Sedan. Although I loved the Sedan and miss the car, I'm glad I went with the G37. Infiniti has made a lot of improvement in quality over the past few years on the G Series. They hit a home run with the new redesigned G35 Sedan and G37. Interior is great, performance is on par, exterior styling is very striking.

Kudos to Infiniti.
