It's not really convertible, but it has no roof so I don't know what to call it! It fits one minifig, small as it is. The doors open and the spoiler is adjustable. There's also a wheely bar and you can see the "engine".
About this creation
I tried to blur the picture to make it look like the car was moving...but apparently I have a quality camera!
An odd shot. Rear view AND open door view combined to save memory on the camera.
You wont believe it,but I built a car very similar to yours,especially the hood and the windshield and its red!!! Apparently the difference is that my lego sports car has a rear engine. What a coincidence. I will posted tonight so you can see it!!
