If you really want Big 3, 3 rows of seats, and not a mini-van, you don't have too many choices.

Kiplinger likes the GMC Acacia in this slide show of 2007 "crossovers":

I'm sure the other GM divisions (Buick, Saturn, etc.) have, or will shortly have, similar vehicles.

Consumer Reports calls the Pacifica a "mid-size SUV". In that category, only the Ford Freestyle gets a "check" rating among the domestics.

I can't offer any recent first-hand experience with anything from the Big 3, nor anything in this segment.

HTH a bit. Good luck!

Cheers,
Scott.
