I didnt know if there was a list somewhere of compatible cars. I wanted to buy it by Thursday (when my 20% coupon expires) but would have to rush on my lunch and wouldnt have time to shop around and bring it to my car to try it. I am just worried b/c my friend has a Britax and it was fine in her Nissan but she bought a new car w/o trying to car seat in it and it doesnt fit in her Jeep so she cant use it (some issue with the headrest). I know which one I want, I wanted to just run in and buy it. I have a Volvo if that helps.
