Looking to buy, first sports car experiences?

Zetine

So I'm 19 and currently saving for a new car, and the Z looks like exactly what I'm after, so looking at a 2010 MT GT model hopefully. The main thing I'm really waiting for is my insurance costs to go down, as at the moment there looking to be about £4,000 a year, which works out twice the monthly cost of the car itself, so I'm a little ways off as of yet.

Anyway, I currently drive a Toyota Celica GTS, so going from a FWD 190hp car to a ~330hp RWD car is quite a swap. Just wondering if anyone here made a similar change and has any advice or stories, other than the normal 'don't drive like a moron'

Also people say quite often that the ride quality is so-so, and the you feel most bumps in the road, at the moment my car has absolutely terrible ride quality, the back end squeaks a lot and you cant hear the radio when you're going 80 due to road noise. The car is a 16 year old Toyota so I'm letting it off the hook, however is the 370z similar to this? Hard to judge what some people define as 'bumpy ride'.
