Volvo V70 - Wallart

A friend wanted his v70 as a bit of wall art and found a fully metal one which was quite an expensive and large item, with very little 3d modelling knowledge and eager to learn I've managed to trace it out and size it to fit on a single bed making it 29cm in length, I've only extruded a few mm as it is relatively small, any thicker and I reckon you'd lose some definition at angles but if requested I can add a thicker one. There are no mounting points as it is very light and it can be held up with some double sided tape or a few bits of blutack to make it stand away from the wall slightly and give a shadow. I'm working on making it bigger, over two beds and 3, but stuck figuring out how you would piece it together which is proving problematic.
