When I owned a Peugeot 406 Coupe, I bought a die-cast model of it. Can't remember the scale but was about 6" long.
I took it apart, painted the seats red and sprayed the body silver to match the full size one. Even printed some tiny matching number plates.
When I part exchanged the car, I left it in the glove box as (hopefully) as a surprise for the new owner.
