To put some slight perspective i dreamed of owning a Supra at uni, did the sums and quickly dismissed the idea!
Been out of uni four years this summer and have just went about importing a car. By the time it gets here i'll be 26 and i'm struggling to find insurance under £1000 and thats as a second car on 3-4000 miles a year!
As has been said, if you're intent on getting one i'd recommend a SZ in the meantime. Get out of uni, save some money then get a TT6! Also worth bearing in mind that Supra prices, especially TT6 cars in good condition, are on the up in Japan as cars are getting harder to find.
