Car designer needed

Hello, I need graphic designers for making of images (artwork, 3d, pixel art etc). This is going to be long term relationship because I will need additional images in the future. The main theme is cars. I need 3 cars custom drawn that can look similarly but could be customized further if I add additional objects on them. Simple example is: [login to view URL] You can see how various objects are added on a 2d image so they look integrated. Now, I need jeep, sports car, convertible. I need them to be as similar as possible so in the future we can add parts to them like tires or hoods etc that can fit on all of them. It would look like a car builder. First I add the body, the doors, etc... everything is separated in different file, so the compiler would pick the specific part and add it to the car. I don't have specific requirements about the cars but they should look nice and professional. In this project I would like also additional pair of front lights to experiment with my software. Please show me previous works. Thank you
