Thanks John
at the very least the nose molds should be rescued.
as for frames and suspension, it depends on your objectives in terms of reviving Rotus. I'm sure several other people will validate this - this business is at best a hobby unless you are going to do it at the highest levels (like Ariel, and the top 2 or 3 kit manufacturers in the US).
I don't think an investor is desirable, nor needed. Investor = return with interest.
If I had the choice for a clean sheet design or starting with the Rotus design - knowing what I know today, I'd probably start fresh. This is NOT a knock on Rotus. I think Chris got a lot of the basics right:
Tank in front of the rear axle is a great safety feature, but at least in my car, it really limited leg room
Inboard suspension - pretty nifty setup. I'm not a big fan of the cantilever design - I'd opt for pushrods.
The rest of the frame design is pretty straightforward and non-controversial, so most new sevens won't be significantly different.
