Should i buy or not??

Right now i have a 94 single turbo supra and i really enjoy the looks and performance this car has but it grabs the cops attention to much if you know what i mean. I was thinking of selling it for a g35 coupe 6 spd. I was just wondering if these cars have any problems or are uncomfortable or drive shitty. I cant test drive one as i would not qualify for the loan and they dont believe i have that much cash since im only 19. So would you buy one over again and what are some up and downs for this car?
