IF you want to stay with VW I can heartily recommend the new Scirroco. A friend has the 2.0T and it's very rapid. Boot is a bit small but it's very nice inside (the car, not the boot!). If you're still after a convertible the new A3 is very classy, as is the BMW 1-series but both are very over-priced (IMO) for what you get and certainly not worth the premium over a similar spec Eos.
As my Eos is booked in for 2 leaks to be investigated at the end of this month I'm convinced that I'll be trading it in soon also (only had it 4 months) for something just as lovable but slightly less 'leakable'.
Come to think of it, think I'd wait for the MkVI Golf GTI in the Autumn. I had a MkV and it was excellent. Same engine (and reason why I bought the Eos) as the Eos but without the susceptibility to let in water!
