While some of you may hate on the OP, I can sympathize. I can't stand how difficult dealerships make it to test drive a car. If I am going to be spending the next 5 years in this thing, I wanna be intimately familiar with it. That includes matters of ergonomics, performance, cabin noise, space, etc. Some of these things cannot be ascertained properly without spending a decent amount of time in the car. In my opinion, it's really best to borrow a friend's car to figure out what you do and don't like. I wish I could rent some of these cars for a day or two. I think Saturn actually used to let people test drive the car for 24 hrs or something (not that I would ever want a Saturn, and look what happened to the company). But I find it ridiculous that a salesman would that I am ready to buy a car after taking it for a 10 min spin. FWIW, I have also found that if you have an impressive job title, it's easy to get test drives. However, you still will get hounded by awful salespeople in terrible clothes. GT-R is a difficult thing because not many people have the car, so it's unlikely that you will have a friend that will let you take it for a spin. Maybe look for a used one on Craigslist or Autotrader. I am sure a private seller would be more accommodating.
