Owned 10 years, over 185,000 miles on it, still going strong. Repairs relatively minor: brakes, belts, that sort of thing. Amazingly, still riding on the original transmission. If you need to move a lot of people and their stuff, she's beast of a workhorse. Because it is so big, the MPG is very low, around 12. But she's amazingly easy to handle, and park, and the visibility is the best of the big vans. Very reliable workhorse. Minor issues: drivers side window failed at 70K. Door lock panel fell inside door. Interior side panels got loose at about 100K. Tires are expensive to replace. But she's been one of the best vans we've owned, and we've used her hard!
So much room. Feel very safe when driving BC of huge size. Great visibility, strong braking. Solid and reliable van. Rear doors open way out, very handy. Seats are light and so easy to move in and out. Strong AC even in the back.
Fix the Chevy drivers side automatic window issue: everyone I know with a Chevy has this problem. Better adhesive on interior panels.
