Is there much advancement in that space? I would love to get a panel van in the nearer future but I won't buy a combustion car nor do I have 50.000 € to to spend on a new eletric one. It would be great to be able to get an older MB Sprinter with a motor defect and to retrofit it with some standardized solution. The last time I looked up on that, the only option was to get a very custom solution which wouldn't be feasible due to the high cost for planning and certification.
