I got my 2018 SV for about 15.5 after rebates, new!
There are a few things I'd like to see beyond the obvious "more range"
Reverse parking sonar / sensors
More than 1 usb! Rear USB too!
Rear AC vents
Cross traffic alert that beeps more than just one lousy time.
Unlock by touching handle (not button on handle)
Premium audio available on SV
Set a charge % to stop at (!!!!)
Powered passenger seat
Bigger Center screen (though plus models are slightly larger)
Better screen interface - its OK. Just OK. My 2018 outback is far superior, with built in APPs, quicker, and much better layout.
DIGITAL Speedometer. There is one page on the left side that has it, so I leave that display on. But look at Kia's design, they always have a digital speedometer up, allowing more flexible use of the other screens.
Two inches more rear legroom.
Plus a few other nitpicks here and there.
Most of these are just things they probably cut back to save some money to afford the battery, but I'd like to see them.
Most other cars have them.
Still, I love our new leaf. And quite honestly, I personally think the 2018/2019 leaf is about the best LOOKING EV on the market. I really like the hatchback design!! YMMV
