Thanks, I haven't followed the GT500 so it's good to know the differences
There is a plethora of info on the web about these cars. The time to search for them could be overwhelming. Some people will give a "do a search" response. Hopefully, the good people on this site will be more understanding than I have seen on others.
The major one to worry about is the tranny issue. There is a thread in this forum about it. read up and see what the issues are. My early 2008 seems to be free of the issue.
Other than that, both years are awesome cars. If you can get your hands on a 2007 at your price, I wouldn't hold back. If your '07 happens to have the issue, people on here can lead in the right direction to get it fixed.
Good luck, hope to see you posting pics of your new GT500 soon.
