good morning my name is ***** ***** I will assist

yes, the northstar has issues. over the years it has got much better. make sure you check the history of the car as well as service records. I would not let that stop me from purchasing the car unless you find something in the past. if it is a dealer, you can tell them you will accept the car if they give you an extended warranty on the power train.

how is gas mileage
Expert:  Roy Belding replied 1 year ago.

fuel mileage is less than the 3.9

I would look for an extended warranty from someone like AAA for the powertrain and deduct that from the asking price.

water pumps were a common failure for this motor over the years. my concern is progressive damage such as a head gasket. I would also have a shop check the car over paying particular atention to the engine
