This is an Audi R10 TDI (1:10 scale) totally made of set 8653. It isn't finished, but these pictures are from the chassis and with the chairs in it. This part took me about 1.5 houres to break down the original 8653-model and about 2 houres to build till the point at the last (second) photo.
These are the pictures after the third day of building:
As you can see the model is finished.
(I'm sorry for the unsharpness of the pictures)
