I agree, don't rule out a TT. It's my first Supra and I went for a TT, I went straight from a 1.5 16v Honda Civic Coupe, huge difference in power as you will all agree lol and I too bought a Supra at the worst time of year (end of November) but I do treat it with alot of respect (OK no comments on how fast I was pushing it on the way to the midlands meet sunday! LOL). I did have alot of advise before I went for a Supra off the brother-in-law who has owned a TT for a few years now, and I was warned about what a widow maker it can be. At the end of the day the car will only be as reckless as the driver in my opinion.
As Scooter said insurance could be an issue if your young, no problem here as I have insured the Supra fully comp for £430 per year (I am getting on a bit, 29 years old), less than it was costing me to insure the Civic?!?! Crazy I know. I did find and so did friends and family that if you include your Mrs as a named driver it knocks about £150 a year off!.
N/A or TT, no doubt you will hear arguments from both sides, it's all down to personal preference and what you will feel happy with. I wanted a UK spec so hence I had to go with a TT. You could always buy an N/A and NOS it up for that extra kick like Ray did. Yeeeeeeeehaaaaaaaaaaw!
