My 'scratch building' as far as bodyshells go has so far been limited to wheelarches but I love seeing other peoples work, especially bodyshells.

Chassis are easy, they're flat and have straight cutouts.

Wheel inserts can be made with old wheels and a dremel if you don't have a 3D printer.

Then there's the decorating, another skill I'm lacking.  Making a model look remarkably similar to a 1:1 'real' car must be a labour of love.

For some of us, it seems that how it goes on the track is secondary.
