Fonix and Blockcube, thanks my friends. Once I have a computer capable of rendering all of my cars at once, within a month, then maybe a car show would be possible.
I’ve always had a long term plan to make an animation using all of the cars I make. Perhaps it should start at a car show.
I have a friend who is working on a city for the cars to race round.
BgDM, thanks mate. I had meant to put BgDM approved on the material name for the paint, in the material library. 
Falgor, thanks. I’m grateful for your reply. Maybe with a better render or two I could sway your opinion on the car. 
digitalSlav, I’ve also been waiting to make this one.
You are quite right about the door moulding into the vent, I’ll have another rework.
The windows are just glass at the moment, I’ll sort the rubber whilst finishing the interior. (Roof lining, door linings, pillar linings, dash etc.)
Quick rear render at the bottom of this page.
A few more tweaks to come, left a render going and will post this tomorrow.
Thanks for the advice, keep it coming.
Sonix.
