With General Motors doing away with its minivans, vehicles such as the GMC Acadia are intended to at least partially fill the gap for three-row vehicles capable of carrying several passengers and their gear. As is the case with most crossovers, the Acadia's shape precludes third-row comfort and ease-of-entry offered by traditional minivans, but the innovative Smart Slide second row seat makes it relatively simple to reach the back row, and the rear split bench is about as comfortable as you'll find in any current crossover. The seat is flat, though your gluteus maximus will appreciate the ample cushion, and taller riders will applaud sufficient headroom. Anyone over 5-ft.-8-in. tall might long for extra leg room.
