Hi JoJo,
I can't recommend that IS enough, my mate at work has just bought himself a TT c/w 18" alloys, but he still likes to play in the Lexus as well - and he seriously thought about buying an IS Sport. I agree with all the other guys about the image, the looks you'll get etc - it never ceases to amaze me how many people stop to stare at my IS - and soooooooo many people say that they want one (but they just can't have one!)
As the advert for Lexus says - it's the feeling inside - and that's true, I spend an awful lot of time behind the wheel of mine, and I always get out having enjoyed the journey - the stereo is class, the seats are comfy and well, it's just all round good fun :cool:
Enjoy your IS200 - you won't regret it!
