Sounds very like my dilemma - had 2 x TT's, c/w baby seats - loved them. Then a 911 - surprisingly practical, actually. Currently car-less and thinking about all kinds of things. Would like a Brera, and tried the 'will they fit behind me' thing with one, but, unfortunately, no. GT perfect. But there again, so's the RX-8..........mmmmmmmm
As Stori says, genuine 2 + 2's are hard to find - I don't even know why they bothered putting the +2 in the Brera, when no-one I've ever met managed to use them.............it's a real missed opportunity if you ask me.........
What seems to be the problem - and this applies to the TT too, btw - is not the actual size of the car etc, but rather that the rear seats are made too deep. The reason they work in a 911/944/968 - and I've looked at a 944 Turbo recently - is that the seat bases are shallow. I did toy with getting another TT and removing and shortening the seat bases. Drastic I know, but I'd hate to end up on the wrong car over something as relatively easily curable as that. Whether that'd work in a Brera remains to be seen..........anyone got a pic of a Brera with rear seat base removed...???
