There's a few different things to consider before I chose obviously, but if I was spending $40k+, a lot more options start to present themselves
GTR would be mainly about performance, while still looking good
V35 would be more a nice cruiser first and foremost, but I only like them if done right, so it'd need to be low with a fair stance etc, supercharge/turbo would be nice but would probably be a longer term goal
euro, not sure what I'd get if I went down that path, but like I said, if you're spending 40k+, you'll have a bit more to choose from...
