Do I regret leasing the Leaf?
NO.
Would I have regretted buying the Leaf?
Not at this point, but perhaps later.
Are there things that annoy me about the Leaf?
Absolutely. Although I don't think there's a car in the world that I wouldn't have SOME complaint about. No vehicle is the perfect car for everyone. There are always tradeoffs.
Do I wish it had a longer range?
Of course! I wish it could go 500 miles on a single charge. But I also wish it could be recharged in 10 seconds, that it would cost less than $10k, and that it had the performance characteristics of a Lambo with the functionality of a minivan. Some things are just not realistic to expect, at least at this point in time of EV technology.
FOR ME, the Leaf is a very good fit at this point in time. I feel it's a very reasonable tradeoff between functionality, range, and price. That said, it's definitely not for everyone, just as no single car is adequate for everyone. Each person/family has their own unique needs. That's why there are so many different types of vehicles on the road.
Ideally, I want a vehicle like the Leaf, and another that would be a like plug-in hybrid (diesel) version of the Murano. Something that would normally have at least 40-60 miles EV range, but can go long distances and pull a tent trailer or boat and be loaded up with all our crap. Eventually, hopefully in the not-too distant future, that's what our garage will look like!
