Audi or Volvo?

I'm in the fortunate position of being able to choose my next lease car - up to £25k. So, what do I go for?

The Audi A4 or the Volvo S60? (I hate estate cars, hence the S60 and not the V70)


So, any comments would be welcomed. As I test drive each, I'll be posting what I think about them on here.
