We bought our Montana new and have had very good luck with it. We just got back from another trip to NY and got 28 mpg.. very good for a 4,000 lb safe vehicle. We get approx 30,000 on a set of average tires and 30,000 miles on brake pads, unlike stories I hear from other vans. The body looks like new. The galvanized body panels are the best, they resist rust better than any other metal. The original stainless steel exhaust will last much longer. It's still in great shape. The interior does not show wear after all this time. The best interior material we ever had. Our Montana has moved, hauled and transported many kids and material. We will be buying another Pontiac.
Build quality. Stainless steel exhaust and galvanized metal body. 28mpg, good strong engine.
The first part to break was a AC line leak after 8.5 years. Estmated repair $150. Not bad for 8.5 years.
