"pure freaking awesomeness (no I'm not 17)"5.0 starson by btarabishy
Pros: Sexy head-turning styling. Gorgeous interior. I get compliments wherever I take this thing. Beautiful engine sound. Awesome power. Perfect package of style, performance, and luxury--and all-wheel drive safety. By far the best value in its class.
Cons: Small trunk.
Summary: Blows the competition out of the water. IMHO, one of most beautiful cars on the road and still (relatively) affordable. It is completely beyond me that someone would choose a 328 or A5 over this asides from being a German car fanboy. A 335 is competitive, albeit a tad faster and more expensive, but frumpy looking and you'll be looking at ~55k if it's well-optioned. If you're considering a sports coupe, you need to definitely give this a test-drive--be sure to take it out on the highway to get a feel for the mid-range acceleration which is pure freaking awesomeness.
If the G37's price is on the high end of your budget I would also consider a hyundai genesis coupe 3.8 touring. I test drove the Hyundai and was very impressed by its handling, but the Infiniti is the better vehicle with respect to performance, styling, interior luxury, and brand cache/resale.
