After searching the forums I couln't find a definate result for fitting the Buzz combined with a maxi cosi cabrio seat in my MCS. Finally my local store has Buzz in stock and I been down this morning for a test fitting.

You need to remove the wheels and seat portion from the Buzz. This is very easy and quick to do. The main chassis and the wheels will then fit in the boot with the pacel shelf left in place. The seat will fit in the back behind the front seats. The Cabrio seat has been tested and thankfully the MINI seat belts are long enough for a good fit. It's rather tight getting the seat in and out though.

Strange thing is that we also took our Mondeo down there and all the seatbelts were too short so we need to get them extended!

I hope this information is of some use.

The Buzz is bigger than it appears to be from images then, but glad it can be made to fit. The Zapp is so small, and such an easy fit, I guess I expected the Buzz to be similar.
