Other than a Suburu (not a brand that's ever rung my bell) you mentioned earlier, I don't know what you're comparing it to. I do know that any reviews I've read have been very tepid with their praise, and I saw an article recently that mentioned that the leaf was third from the bottom as far as resale value after 5 years went. That's gotta say something.
I thought you only have had this car for a couple months...you haven't even seen a cold morning yet. See how well that heat pump works in Minnesota in February!

Oaktree one thing that it says is let the first owner take the depreciation hit by buying a high end car at a much lower price. The Nissan dealer did not come down from $16,000 to $13,416 in only one step because they had 12 people lined up that was willing to pay the $16,000. :)

From your posts about EV's I take it you do are not speaking from first hand knowledge about any EV. It took me about a month or two just to read through the bulk of 10 years of web postings about the Nissan Leaf. After deciding I was good to go with a first time EV getting our sixth Nissan was an easy choice because Nissan is a high value for the working class folks. It not having a gas tank or transmission did feel different for sure.

It was amazing to find a used deep blue pearl (new color added in 2016) Leaf SL not only with the top level trim package but with all the factory options offered by Nissan. 2/5 years of Nissan coverage on the drive train/battery was a nice bonus. I was sold on the Leaf before making the 4 hour drive in the F-150 so I could pull it home. It took them about 30 minutes to decide what they wanted my money or their car the most.

Now that EV's are moving more mainstream and more options are coming to the market the fad status is going away. Nissan does not have the high end sound to it as saying I just bought a 2016 Tesla with 22K miles on it that looks new. :)

When it comes to used cars I do my research then lay my money on the table. Mentally when I buy a used car I ask myself if it is a dud and a total loss will life go on more or less as before. That way I take the full loss upfront mentally so there is no stress down the road if things do go south. I practice making fast decisions after I do my research and then being slow to change my mind after the fact. The opinion of others besides my wife are not something that I use in buying a used car especially that is for taking her to work daily since she hopes to be able to work until 70 to max out her social security and other retirement income. That should about get the daughter out of graduate school potentially.

Looking as if a vehicle is new was a plus with this 2016 Nissan Leaf SL as well as the leather heated seats and steering wheel. After the car was parked about an hour at about an hour at 10 pm tonight the air temp was 24F and I could start to feel the heat pump working some in 20 seconds but in 30 seconds there was good warmth. Front and rear decks and the 4 doors have great fitment with a nice solid sound when they shut. The handling and ride are awesome just comparing it to the 50 years of used car ownership. While the sound system is awesome it was the 4 exterior cameras was the part of that $1500 option package that I wanted to help limit the impact of my limited physical range of motion. Now full self driving is on my list sooner than later but they are not out there on $10K-$15K used EV's just yet.

It sounds like to me you are thinking about EV's more and more. That is a good way to wind up owning one. I do see one in your future. :)

Not sure if this has been posted, couple of GM related stories and 2 on Tesla Production

GM is building a new battery production facility with LG Chem and investing 2 Billion dollars.

The Plant will be able to produce 30 Gigawatt hours of batteries per year

That is 50% More than Tesla's US Gigafactory production

As an example if GM builds vehicles with 80KWH battery packs, they could support production of ~ 375,000 EV's per year Also,

GM's Lordstown Plant was sold to a company that is going to produce the Endurance EV pickup for fleet sales

Lordstown Motors CEO eager to move into old GM Lordstown plant - YouTube

Over 300 model 3's already in the lot ready for sale?

More than 300 Tesla Model 3 made in China seen parked in Shanghai Gigafactory 3, ready for delivery - YouTube

Tesla Gigafactory 4 is aiming for 500,000 (Model 3 and Y) vehicles per year

I do not think I knew about the Endurance EV PU. Going for fleet sales I thought would be a low margin product?

Are legacy automaker's EVs officially screwed? - YouTube

Are legacy automaker's EVs officially screwed?

If most EV makers are using the same battery source they will more or less spec the same performance and range wise.

It seems to me that the battery in the EV the tail that wags that dog. EV batteries= ICE engine power. Electric motor technology seems important but not as much as battery.

Electric motors have not caught the eye of Modern Media. Much easier to boil everything EV down to "battery!" and "range!" "Must have EV chargers on every street corner because we have gasoline stations on every corner!" Just as, "The Civil War was about slavery!" Easy way to make people think you are smart.

Tesla has gone through several generations of electric motor design and manufacture already.

The Model S started using a 3-Phase 4-Pole AC Induction Motor, of the brushless variety. Great for mechanical simplicity and lack of need for so-called "rare earths". But it is not as efficient as a permanent magnet motor due to need for use of power to produce both sides of the magnetic field. Permanent magnet motors use an excited coil to push against the magnet.

An advantage of the induction motor is it freewheels when unpowered.

The Model 3 uses a Switched Reluctance Motor. The coils in the stator are switched to pull the solid ferric (usually a laminated soft iron) rotor around. In textbook designs no permanent magnets are used. The SRM is essentially a stepper motor which doesn't turn smoothly. Recent developments in motor control have solved that problem, plus the discovery that the use of relatively small permanent magnets in the stator improve efficiency and smooth torque delivery.

Sneaky old boring motors.

Just saw the Mustang is going electric. Four door! Like they said, can't be any worse than the Mustang II. Sales on Mustang and all such cars steadily declining,

Well I learned something new about the Model 3 motor design.

I am about 2/3 through the first read of Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future by Ashlee Vance 2015. What the guy has been through and still is changing the world of earth and space vehicles is mind boggling.
