My 1.5" Tall Model Cars

Hey, there, recently I have been making some model cars. These all are 1.5" tall, so a bit taller than a Hot Wheels, yet easier to see their detail. I have made a Fastback Muscle Car (Seen on the cover), a 20's Limo, an 80's Pickup, and an ‘Exo’ Race Car. If anybody has any suggestions, ideas, or cars that they would like me to try and create, I would love to find out!
