Re: purchasing a 2000 Taurus
I had a 01 with the 3.0 flex fuel 12v. Had one major issue, the transmission would overheat occasionally and spit fluid out of the vent hose. I replaced the coolant recovery tank that would seep and cause the radiator to run a little low. Not for sure if that was the cause of the overheating (more that likely was) as I traded the car off shortly after.
Other issues, ball joints, rotors, strut bearings, water pump, cam synchronizer assembly and the windshield has a slight leak around the seal. Also the fuel gauge stopped working right after the warranty ran out, which turned out to the the flex fuel module. I traded the car in before the 100,000 mile mark.
Overall wasn't a bad car, but I expected it to be problem free at least to the 100k mark.
