quite a bit but less than the cost of buying a new or used Tesla
If you already have a cheap run around (like i do) i find the supposed affordability of switching to an EV fairly laughable but there is a point of view that the resale value justifies the outlay if you can afford it. Doing a conversion is always going to be personal thing that will likely not have much resale value. Similar to heavily modified cars or overblown restorations you won't see much of that investment back so i'd want to be confident it's a keeper. I wouldn't be surprised if insurance premiums were a lot higher as well given the limited numbers of insurers that'll touch a conversion.
All that said if you find out more do share the info!
I'm guessing a very spendy conversion but as posted above there's some forumongers that should be able to help. I've been thinking about the same for my Saab 900 to justify the cost and work of doing a restoration on it. Can't see the point of pouring money into a car that i won't be able to use in the future. Guy Martin did an episode recently with some behind the scenes on a conversion company. Not really a fan of his but some cool conversions on show.
