These two models have plastic body.
Chassis is diecast.
I found these when Roland was talking about bodies with another member on SCI site.
Engine sure looks nice through the back window.
I only put engine and dashboard in to this car but rest of the interior looks good too and it's made of plastic. I can send you a picture of it.
With gift card chassis you could add that too, only need a driver figure after that.
Cheers
