Thank you sir -

I did go to the dealer yesterday and I was able to place my 2 radian Premier as well as a Britax booster in the middle (Britax booster are thinner than Sunshine booster surprisingly).

It is tight but it fits. I was more concerned about the leg room cause i felt my oldest son will always be banging on the back of the seat but my wife thought it wasn't that bad.

Then we went test drive a Cayenne 2011 just to see if the fit would be better. The width was the same but there was a bit more room. However the waiting time of 10 months to get a car killed this possibility. We also looked at the Q7 but i really don`t like the look at all.

After discussing with the wife - we decided that we will go Q5 even though it is a bit tight. For longer ride we will use the Honda Oddissey - should be all good.

I will look at the Chicco to see if they are not even better than the radian. Any inches i can get would be good.

thanks for your reply, much appreciated.
