2001 Chevrolet Astro Rwd 3dr Minivan (4.3L 6cyl 4A)
I had a 95 that only was in the shop a couple of times for non-maintenance work - a bad EGR valve and the exhaust system rusted out at 92k miles. Based on my experience I bought a new 2001. It's five years old and has 120k miles on it. I've had a few non-maintenance repairs. At around 50k miles the turn signal switch went out. This was a $450 repair but about three years later, GM had a recall on the switch and re-imbursed me. I installed new front shocks at around 70k miles. At about 105k miles the fuel pump went out. This cost $750 plus the towing!
Lots of room. Much more room than a small mini-van. Heavy duty vehicle compared to other minivans. A good value for the money. Plenty of power. The van can pull a trailer with no strain.
The quality on the 2001 was slightly lower than my 95. More rattles, interior trim items that came loose, etc.
