I've bought used for every car I've had so far. Just find a dealer that offers a warranty for used cars.

I drive a VW Rabbit right now - 2008 and I bought it towards the end of the 2008 year. Had like 10k on it, paid $9k less than new price and it came with the standard 3-year new warranty in addition to a 5-year used warranty so I have warranty until 2016.

Planning on buying used next time around too - the price difference compared with new can be massive.
