my bully fits perfect in back. he's still a pup though.
my other bully who died earlier this year was about 120 pounds and while he might not have had much room to romp about he still would have fit comfortably. He was quite mellow, so he would have just enjoyed view out the back window, and the snug fit would have kept him from trying hop up front. in his last days i had to handle him quite alot for car rides to the cancer treatment clinic, and with that experience i can say confidently that he would have fit snugly yet comfortably in the back of my smart.
i have the luggage compartment roller-divider, which does a good job of creating an area for little kosmo to feel comfortable in while we go for rides about town. sometimes he'll sit upright and face forward with his paws resting on the divider, content to watch where we're going, or even take a nap. other times he'll just look out the back window as people wave at him.
while i havent yet tried, i suspect that folding the passenger seat flat-forward would accommodate his carrier, which im quite sure is a bit too big to fit in the luggage compartment.
