I'm going to have to look some of these cars up! England is a looong way from the US.
For the Lotus, it started off as a CAD model


Then after being scaled to 1:32 and adding body posts it turned into an SLA (3D print) model


I made a 2 part silicone mold and resin cast the bodyshell and wheels



Windows and interior next.
Keep the ideas coming!
