Although I don't collect Matchboxes with regular wheels, they sometimes appear in my restoration program. Just like this Matchbox Ford Zodiac Mk4. When I saw it the first time, I knew that it will be a police car - the Lesney only produced as a civil one.
In this case the body and the windows were ok, needed no spare parts, so I could start the work.
I had to drill a hole on the roof for the rooflight which was originally a miniature LED bulb.
It got the white colour, and I designed for it a unique Police Car decor, which should be somehow similar to the real UK police cars.
At the end it got an own L-type box, too.
