A TT is hardly in supra territory though
A bit like saying a TT easily beats a Hyundi coupe...
To the OP, are you talking about buying new?
The new subaru I recall shares a lot with the Saab models, but the engine and chassis are still very good. If you get a discreat silver one then fine, but the blue ones seem to make them either want to race, or be raced at every set of lights.
The new TT is fairly exclusive, but how long before it goes the way of the old shape? It wll hold its value for longer though.
I'd go for the Nissan 350z over the TT anyday, and probably an Audi S4 over a Subaru to be honest. But if you want cheap and fast, the Focus ST I think will take quite a bit of beating, at the danger of being more chavy than the Impreza
