I’ve been very happy with the car. No battery issues, though the range is pretty comparable to a first-generation LEAF. Not long range, and without quick charge capability, it’s really limited to being a commuter car. But it’s a very comfortable, solid, and peppy commuter car. My kids love the back seat.
I have run into issues getting my car serviced though, just like you fear. I live in North Carolina, so the car isn’t sold anywhere near me. Most dealers around here won’t service it either. My local dealer won’t even touch the standard non-electric stuff. I wound up having to get the car towed to a dealer about 150 miles away (in Tennessee) for routine service, which is a major inconvenience but at least MB is footing the bill. Fortunately, I’ve never needed anything other than the standard preventative maintenance - which is mostly just conditioning the battery.
Even though I’m thrilled with the car, I would have some reservations about getting it due to the lack of readily available service. What if something really serious happened? You might have to deal with a shop hundreds of miles away.
If you’re able to find a service arrangement you’re comfortable with and don’t plan on needing it for Tesla-style car trips (which are at least somewhat doable with a LEAF due to its quick-charge capability), then this would be a terrific car for you. If you live in a blue state where the car was sold new (it’s just been discontinued), then chances are your dealer will support you.
