I own an 03 plate TT coupe 225 BHP.
If you are after a quick car that is sporty yet still a nice place to be and comfortable on longer journeys that the TT is a worthy contender. It doesn't have the same feedback the likes of the S2000 or 350Z has, but it is very quick (sub 6s 0-60 with a remap) and has bucket loads of grip.
It is also far less chavvy then most alternatives, and doesn't feel like a cheap family hatchback with bits bolted on (Focus ST, Astra VXR, Impreza, Golf). Yes I know the TT is fundamentally a golf, but it is a whole lot nicer place to be and is in my opinion one of the nicest looking normal cars on the road.
Like any other TT driver I have been subjected to the odd "hairdressers car" comments, however I fail to see how a 225bhp (270 with a remap) 4WD coupe is anything like a hairdressers car, particularly when the majority of comments come from those without a car or drive a T reg Fiesta. I also get far more comments from girls wanting to have a look at it or sit in it, which would be great if I were still single.
