What do you think of my car design?

It will have carbon-fibre rims, an n/a V12 engine,available front or mid-engined and will have a retractable metal thing on the rear bumper to help with reaching the engine,retractable wing mirrors,Lamborghini style vents that open at high speeds and the way to get in is to move the window to the right. I’m also planning to do the rear of the car in a few days!
