A bit of a change from all the truck kits this. I have yet to start on mine. Not cheap (now around £60) but you get a lot of plastic for your money consisting of 192 parts. The (big) box is full of sprues and by taking them out to check them you run the risk of not getting them back in very easily!!
There are plenty of seats to paint... 55 for passengers plus the driver. There is an MAN engine sitting in the rear which will need painting. I presume construction has similarities to the way the actual coach is built with some nice large areas requiring some paint.
The two doors open to get a better view of the interior (a removable roof assists here). At 510mm (about 20") it is a sizable "lump" when completed.
The best I can do is this picture from the net courtesy of the Revell site...
