Just got myself a new Audi A6 S-line Diesel Ultra, which is costing me £375/month on a four-year PCP deal. It has very low vehicle tax, and comes with a nice, plush interior. Admittedly, I'm on a deal for 10,000 a year, so it would cost you more on your mileage, but I'm loving it so far. Basically, your monthly payments pay for the depreciation of the car to the end of the contract, and at the end you have an option for a balloon payment of about £15,000 to buy the car outright, or you trade it in at the "guaranteed Minimum value"
