If it"s a later 2000 and has the 2.7 liter engine pull the dipstick and see what the oil looks like..Also take the oil fill cap off and see what you can see...The 2.7 has a history of sludging up the internals and dieing a premature death...If it's ugly in there I'd think twice about buying it...There's a bunch of chryslers around here with the grenaded 2.7s that the owners don't want to deal with..
