What sort of work do you need?
One advantage of an EV is that most of the complicated systems found on a traditional vehicle, especially the internal combustion engine and transmission, are not present.
The remaining systems such as the brakes, coolant, reduction gear, or tires are quite simple and can be dealt with by any mechanic, including most at-home DIYers.
The only time I would consider taking our Leaf to a mechanic or Nissan dealer is if there was an issue with the electric motor or battery pack.
