Seems like there’s potential space in a lot of the undercarriage, or as flat packs at the base of the engine and trunk compartments.

There are some companies working on electric crate engines for conversion, I forget the names but they should be ready sometime soon

Ford has at least one now, I think VW does as well

…and that’s when I bought the horse a prostitute.

Least I could do?

Depends, are we expecting the sub to survive?
