I tried to fit 1 rear facing and two forward facing in my 2011 Jetta with no luck. It was about 3 inches too short, and you might just have those 3 inches in your bigger back seat (I'm guessing). Measure your seat width from door to door, mine measured 5ches. Britax Marathon 70-G3 measures 18in wide, 3 was too much for my car. I put a Combi Cocorro in the middle which only meases 15in wide. I think I could have squeezed 3 in, but the doors would've slammed on them, not safe. Britax Advocate measures 22in wide on the top and 18 on the bottom, and the booster seats measure bigger than most of their convertable models. So you could fit them if they were facing opposite directions. Say 2 rear facing on the outside and forward facing in the middle. Babies r us will let you bring some of their floor models out to your car and try to fit them. I had to go 3 seperate times, it was a huge headache, but worth it to fit Britax in.
