I really like the 818 idea, and just add the pieces to make it look like a 914. Then 914Rubber has the molds once perfected a Sheridan kit on it, cover some monster meats. Then go and
the
out of it!
Door sealing etc... becomes an issue, but it is not bad.
You really only need the cockpit area, and if the car was rusty enough or hit in the front or the rear you should be doing it a favor.
But then I would just build the 818 chassis, put a helmet on, and just drive it, aka Atom, , Lotus 7, early 30s F1 cars, etc....
You don't need all that extra crap really. Yes it is nice, A/C is nice, I getting old and pampered.
BTW, back to the original topic, nice rendering. Now it has to get to physical reality, we will see.
It has been done with several cars.
914 Boxster
904 Boxster
Karmann Ghia Boxster - my favorite just wish it was a coupe.
Not sure why to start with a Cayman, except Boxster is to played out.
