Re: 2000 Taurus - buying advice
I own a '99, different exterior but nearly identical mechanically and I have 190,000kms on it (118K) and no major problems to report except for regular maintenance items. Seat belt spring was replaced under warranty at 30K; both front wheelbearings at 68K; alternator was just replaced a month ago; muffler is getting louder by the week and will soon be replaced. Otherwise, I've replaced nothing other than fluids, brakes and tires.
If I were you I'd take it for another test drive, make sure the owners manual is in the glove box, check ALL fluids you can find a stick for under the hood to make sure they're clean and not black/gritty looking.
I'd buy another one also. My '99 2V 3.0L V6 has served me well with nary a complaint except being a bit underpowered on the highway when loaded with people and gear. For two people it rides great, gets decent mileage and parts are reasonably priced, even at the dealer. Expressway Ford service has been outstanding as well where I had purchased the car as a demo model. I think I'd get a 2000+ just for the newer body style and larger fuel tank (2gal more).
