We have owned two. Trouble-free EV and trouble-free motor. The over-engineered little electrical actuators (for trunk, for gas-door opener) were our maintenance costs. The US only offers a single, dreadful tire in the correct size (Bridgestone Ecopia), which is the true achilles heel of the thing. The tiny tires seem to be made of discarded twix wrappers, are super expensive, and get destroyed by potholes and road hazards.

They're lovely little city bugs and just a pleasant place to be inside.
