Depending on where you live you can almost build certain older cars from new parts. For the UK I believe you can get every single part of an Morris Mini either brand new or at least refurbished. For France you can probably built a Citroen 2CV for parts, including an EV version.

A friend is doing exactly that with a defender 130 . New galvanized frame, every panel new, new axles, new brakes, new transmission, transfer case and engine. New seats, new interior, new doors. Cool project.
