Yeah so kinda like the first picture !!
'Lightning' I have this video game, It's called Mafia 2 you might have heard of it 'Lightning' or maybe not !! But Anyway the game is set in the 50's in Amercia and of course the cop car which you play on creating is closly similar to the cop car within the game !! Now there was a feature in the game I believe it was like a car showroom type thing, and what you could do was you could view cars, and you could zoom in, rotate slowly or whatever you wanted to do !! My point is if you looked on Youtube or maybe you have this game, using this Car Showroom feature, I believe would defintly help in creating a close realistic 50's cop car !!!
Wow that was the longest post I have posted here on EB !! Phew
