I recently bought a 1995 Chevy Lumina of which no care seat fits. Theres a web site that shows compatibility, funny thing is I actually tried to install a new car seat and it definately did not fit any which way. So I look up the cpmpatibilty list and it stated the Cosco hhb was a good fit. So I preceded to look online where I can buy one. Heres the funny part it's the same car seat I just bought and would not fit in any way. So much for the list. So I put in my daughters car seat from previous car, Cosco Summit hhb. It fit on the passenger side. (I like the car seats in the middle) but the next day I tested it again to make sure it was secure and the bottom pulled out, top was secure pulling back and forth as well as side to side, but when the bottom was tested it just came out about 6 inches. I thought about getting the ride safer travel vest. (only sold in one store and not the right size). But this would be used as a permanant car seat. and needs A tether and of couse the car doesnt have one. but on the web site it says the small can be used with lap/shoulder or lap/tehter. But everywhere else I see it has to be used with a tehter. Well if anyone has any info on this vest ot another seat for this car I sure would appreciate it. Also this car will never fit a seai in the middle whick is a big reason to get the vest. Thanks.
