I was hesitant to trade in my 2000 Suzuki Grand Vitara mainly because I didn't want to give up the 4WD capability. Having one kid and another one on the way however, the lack of back seat room was a killer. The Matrix is just right!! Better fuel economy, plenty of room and I get to keep the AWD for those snowy winters here in Chicago. Before the Matrix I looked at the Chevy HHR and the PT Cruiser, neither one offers AWD and the Toyota quality jumps right at you when you compare them, no contest!!!
Seats are very comfortable. I love how back ones fold completely flat. Plenty of storage space and air bags.
Outside mirrors could be a bit bigger, maybe I'm just used to the SUV size mirrors. Not that I'm going to tow anything heavy with it, but I yet to find out if you can install a hitch on this baby, just for the bike rack.
