The two that interest me the most are the Ford wagon and the Goliath Tiger.....
The Ford would get an engine swap, maybe a 2.0 VW turbo motor with a 5 or 6 speed gearbox, or even a 302 out of a Mustang? The Goliath just a total refurb back to as new.
But there is no way I could take on another project right now. Still, fun to think about.......
