We are two weeks shy of 6 years of LEAF ownership, with 67K miles and 10 capacity bars (~49 Ah last time I checked).
We still use the LEAF for a lot of our local driving, up in the San Bernardino Mountains of SoCal. The car is still good for 50 mile round trips to the east side of the Big Bear area, where we occasionally go for outdoor activities and most recently a star party.
The limited regen is probably the biggest downside of ownership at this point, and the 12V battery has been a problem. We're on our second 12V battery, and I have to put it on a charger every week or two to keep it alive.
Until last September, we were using the LEAF for a good fraction of our regional driving, relying on public L2 and CHAdeMO chargers around SoCal. Then we purchased a pre-owned Tesla Model S, which we now drive everywhere beyond the LEAF's single charge range. Besides regional trips, we've taken the Model S on two separate camping trips, to Zion and Bryce Canyon National Parks on the first trip and to Death Valley National Park on the second trip. The Supercharger network is great, and we love driving the Tesla long distances.
I imagine we'll keep the LEAF as long as it functions. It's great as a second car, and we don't have to worry about getting it dirty, etc.
