370Z or used LS3 C6???

So what rear comes with the base model? Is it the one wheel peel deal? The sport package sounds like an awesome deal! I really want leather & a decent stereo but I wont consider the touring since its a $4000 increase. I have no problem buying a used LS3. I can do a carfax, GMVIS report, & visual inspection. Also, they come with a 100,000 mile powertrain warranty. I called a local dealer about test driving a black Z they have. They said they only let test drives after agreement on a monthly payment? I got the impression that I would have to buy the car before driving it. He did say I could drive it around the parking lot though lol. I will admit, the thought of a new car vs a used one is much more inviting. Here's what Ive come up with so far.....

.25 mile- Vette FTW by .8 seconds (very significant)
Braking- Z FTW by 2 ft (60-0 MPH)
Handling- Z FTW by .02 (skid pad)
Exterior- Its a tie!
Longevity- Hard to say at this point. Both motors are new.
Exclusivity- Z FTW since the C6 has been out for 4 years now
