Time to replace my GF's car. Choices are Mazda6 S, or Fusion SEL. Trying to find nice used 6 to avoid depreciation on a new car, but can't seem to find many nice, loaded up, 6's. Not to mention the 6's have held their resale exceptionally well. Leasing may be an option if I can just keep from modding

. If buying new, price range is $20,000-$27,000. Used up to $15,000(won't finance). Car has to be 4 door, no rear wheel drive, auto

, and loaded up.
Thanks for input!
