What's a good company car to get with a budget of £25,000?

I've had a Kia Sportage as a hire car (which I really liked), also a Toyota Rav 4 (which is out of budget and was rubbish compared to the Sportage). It doesn't have to be an SUV, just want something thats comfortable with a decent entertainment/sat nav system as I do quite a lot of miles, and obviously the cheaper on tax the better.
