"Tell that to the Pathfinder and Pilot. Their sales are both up over last year's."
The Pathfinder is a good argument, but the Pilot is just an Accord wagon so if you use it as your point GM should be dropping their BOF and going with Crossovers instead. Unfortunately, they won't get any good press over this even though the Xovers will get much better gas mileage.
Also, the TB etc. are too big. If you pay sticker price on them you might as well get a Tahoe, that is only slightly bigger and is a much better design.
