We bought our 97 Chev Venture Ext LS minivan (2 sliding doors) new and have had an overall very good experience. The 2 problems so far are a check engine light at 75K miles that the dealer reset for $80 (has not come back on yet), and the drivers window switch went out recently & cost $65 to replace. We have 88K miles. It was the quietest and best driving vehicle I have owned so far.
2 sliding doors, autoleveling with built in air pump (have used it much more than I would have predicted), room, tinted windows (aftermarket), cruise control,
Rear air conditioning is highly recommended. The 2nd row seats are not the most comfortable, but the kids don't complain.
