I think if you are in @kezo situation, with the knowledge and equipment, it could be a really enjoyable hobby that could also have the potential to make some money. However, unless you can do the vast majority of the work yourself I can’t see that it’s a risk worth taking.
As I say, I have no experience of this so this is a genuine question, but whilst EVs have less mechanical parts, if you buy from Coparts do they guarantee that the battery absolutely has no damage, or all cars sold as seen? Given that used EVs are very difficult to sell even without a crash history, I would have thought that any battery damage means game over?
Maybe I’m naive, but if the cars are easy and economical to repair then why are they written off? Presumably because the cost of repairs using a garage makes the repair unviable, which further emphasises that this approach only really works if you can do the restoration yourself and therefore don’t incur labour costs – just your time?
