Latch system not compatible with newer cars

My wife spent considerable amount of time researching the best car seat for our daughter and she chose the roundabout by Britax. I agreed with her findings and found the seat easy to use and our daughter appeared comfortable when we tried it out at Babys'R'Us. However, I was extremely disappointed to find that the latch system was not compatible with our 2007 Honda CRV. Automobile manufactures have been installing latch attachment points for a few years now, I assume, because it is a preferable and safer way to secure a carseat. Considering the cost of the Britax seat, I would have expected the manufacturer to ensure compatibility with vehicles, especially the Honda CRV which was designed with young children in mind and is very popular with mothers. Britax was unable to provide a latch other than their standard so we are left with using the seatbelt which is harder to install and which I believe does not secure the seat as when as a proper latch system. I assume Britax has this problem for their entire car seat product line.
