I bought a Braun Entervan (a Chevy Uplander that has been converted by the Braun Corporation for wheelchairs) 7 months ago and have had it in the shop 15 times. The ramp was improperly installed, the Smart box failed, the Braun wiring harness was broken, and the Braun applied weatherstripping fell off (I had a GM dealer fix some of these problems). I've also had Onstar problems, seatbelt, and molding problems that are GM issues. The initial quality was very low.
I actually like the styling of the Uplander and the paint is better than average.
