A little late to the party here, but this is a pretty interesting topic for sure. These days, people are turning muscle cars into electric cars and even 3D printing the parts so that the restomod can be reproduced en masse.

Here is another good article that speaks to the pros and cons of each:

Personally, I think it's up to the individual to determine what will make them happiest with their ride!
