I've had one for over a year now as a company car and it's alright actually, but coming from an Audi A4 2.0d it took a bit of getting used to.
It's never going to be a fast car when it's only got a 1.6 diesel engine, but once the turbo's spinning it's fine. Problem is, when it's off boost, meaning less than 1,500 revs [u]NOTHING HAPPENS, especially if you're on any kind of uphill slope. That poor little engine just can't cope without the turbo.
However, you quickly learn to drive around this and then it's just as quick as you need it to be in normal driving. On motorways it's fine, comfortable, reasonably refined & more than capable of cruising at over 80mph and returning over 50mpg at the same time. In my opinion the handling's better than an Audi A4 too, so it's easy to throw it round bends and have a bit of fun with it too.
If you get an SE spec you get bluetooth stereo/ hands free kit, iPod connector, cruise control, auto start/stop, auto hold handbrake, air con, auto lights & dimming mirrors. It's also big enough to get 5 adults & 4 dogs inside too, or several bikes in the back if you fold the seats down.
There's also the small matter of low emissions and therefore low road/ company car tax too. Gave me a huge company car tax saving over the A4 !! It's never going to be the most desirable car on most peoples list, and given the budget and choice on the company car list I'd definately prefer a BMW 3 or 5 Touring, but overall I actually quite like it
