I bought my g35 back in 2003. I bought it the first month it came out. I always hate buying something thats new on the market because you are stuck with all the bugs. The problems I had in my g35 were way to much brake dust, there was a cricket like sound when I was ideling, or stepping on the gas going at low speeds. My suspension really got bad the last year I had my car. I had to replace my brakes every 10,000 to 12,000 miles.

I got my g37 2 weeks ago. I hope I am not the demo tester for future g37's again.

Over all I was very happy with my g35, and I am very happy with the g37.

 

I think they fixed a lot of the known bugs from the G35. Hopefully the new issues that come up aren't as significant or annoying as the G35 issues were.
