First of all, carseats belong in the BACK seat just in case you forgot (unless your gfs mkIII supra had the front seat pushed up so the carseat could fit, in which case I'm sorry for going off on you). But the 240...I wouldn't put a car seat in my car mainly because it doesn't have a backseat anymore

, I'd rank it with the celica, you could still use your front seat, it'd just be more cramped. (I've driven my brother around...I'm way too young to have kids, and don't plan on it for a LONG time...)
