There's a 2004 Galant for sale for $900. It has 180,000 hwy miles on the
odometer, is it a good or bad purchase if nothing else is wrong with it?
Check CAR VALUES at the top of the page or go to websites like Edmonds and TrueCar for values. If the $$$ seem OK to you, have a mechanic check it out prior to purchase to see is the seller is truthful and if there are any problems that should make you walk away.
No one can say if you should buy it or not but you are only risking $900. Offer less!
