Something should be done about that rear door handle..... Maybe making it a concealed handle like a Tesla would help.
This is also my most ambitious project I made recently. I also wanted to find a less tedious way to make a coupe into a sedan, and this one seems to suit me well for now until I'm at a level where I can go with the common strategy.
I had a lot of trouble with the roof, and that's how I decided to keep it as because it'll take me forever just to get the roof right. I'll revise it another time in the future.
