No idea, but would like to know. I have a car that is alittle smaller than yours. I think I am going to have to go to buy buy baby to figure out it out.
I asked the same ? last week!! I ended up getting a Roundabout. I know the Marathon lasts longer...but my older ds has a Regent that we can give to dd when she outgrows the Roundabout. Space is an issue in our car (ds needs space for his legs so he has to be behind passenger). When dh is driving (6 ft), he skims dd's snugride behind him.
