We have Roundabouts for ds in both cars, dd is still in a "bucket seat" , anyway we have found that it fits well in most cars, we have a Ford Contour, and Windstar, we had a Protege, but traded it in for the minivan, the roundabout fit great in all the cars, and we found it very easy to install. We have also traveled with it quite a bit, and rented cars, and never had a fit problem.
