That's a write-off? The book value of a 500e must be very low!... my insurance total 500e and integrating it into my pretty rust free 1978 Fiat X1/9.
Rust-free and X1/9 don't usually go together, do they?... my pretty rust free 1978 Fiat X1/9.
A good body makes the car more valuable (so do you want to use it?) but also makes the conversion easier.
Since the 500e and X1/9 both have the same powertrain configuration (engine/motor transverse ahead of drive axle)
and are not wildly different sizes, the swap seems reasonably straightforward; I'm not saying it won't be a lot of work,
just that radical surgery on the X1/9 shouldn't be required. If you can figure out where to put all 600 pounds of the battery
without ruining the usability or handling of the X1/9, then it could work.
