Before I have kids (and before petrol becomes 'too' expensive) I would like to have a sporty car.

So, I have a budget of about 28k.

I am thinking, for that amount of money I can get a Porsche 911 Carrera S on an 05 plate (997).

Any alternatives?

My wife likes the Audi TT. I can get an almost new one for that price but... it's an Audi TT?!

Opinions welcome. Thanks.
