Well, here are my contributions to Panos' review and I'm grateful for him allowing me to add them.
First, though, I will say that having looked at the pictures I took, there is the same problem with the roof light not fitting flush. Maybe, a bit of sanding in the roof opening is the answer. I wonder if there is a curve in the roof which causes this poor fit?
Now for some photos.
The car is, like the 4223 ambulance car, based on the VW Passat and looks especially smart in the silver and blue police livery. Playmobil has caught the shape and smooth lines of the original beautifully, as this side view shows:
It also looks good from behind with the back closed (note the POLICE sticker):
and open (note the stickers inside the opening hatch complete with POLICE and warning signs so that these are visible with the hatch open and obscuring the roof light. I'm planning to stick on blue "jewels" to represent flashing blue lights too):
It also looks good from above:
and from in front:
These last two photos show off the excellent printing of the ventilation grilles on the bonnet.
