It's a nice idea, but the welding part may be the nail in the coffin. I can hear HSE reaching for the valium already.
There is an alternative though, how about build chassis' to rolling stage. People who have placed an order, either with us or Saturn, could turn up with their parts (diff hubs etc) and build their chassis with the help of both Forum members and the pro's
Could get several done in a weekend
Still, it's a long way off, so keep the idea's coming.
I'm still for organising a Roadster weekend at the Haynes museum, book the track too for a time trial, could be a cracking weekend.
Kind regards
John
