We purchased this Astro as a conversion in 1990 with 18K. It just died last week when the tranny died at 246K. The Astro was a good van, though after 150K miles it started to suck up money. We had prblems with a fuel pump, one window motor, the paint coming off after 200K miles, and the A/C system and hood latch. It also ran through a lot of tires in its time, but it went over a lot of rough roads too. We got our money out of the thing, the Starcraft conversion was excellent, and the gas mileage was decent for most of its career at 20 mpg. The biggest pain was the well documented vacuum hose problem. The bad rap the Astro got for crash tests and bad production values was not true in out case!
4.3 engine had lots of power, and low maintenance costs. Very comfortable to drive and ride in.
At this point, not a real significant question, but I would sure like to see another manufacturer develop a van like the Astro insterad of basing its vans on cars.
