K.A.
We have a four door Toyota Tacoma. My Husband is 6/2, I'm 5/10 and our son is in the 95th percentile for height at 2 1/2. He fits just fine in the back and we're going to be adding baby number two back there in October. There's plenty of room for us. If your looking for something bigger, a friend of ours has the Tundra which is a bit bigger and the option for a front bench seat if necessary for extra passangers. When we were shopping we took our car seat and son with us to check it out. If the dealer really wants your business, they won't complain : )
