We have a Kluger and I had 2 car seats and a booster in it the other week and it wasn't easy to fit them in.I don't think they were ideally secured, I was glad I was only going a short distance. I don't know what cars are bug enough..prob land crusiers etc. Sarah maybe speak to one of the RTA's recommended fiting experts they would come across it a lot. I think Littles (who rent car seats) is one.
