I cannot stress enough about my poor experience with ZEV. The owner tends to come across as a bit bigger-than-life, which can be very compelling if you buy into it. However, he orders his parts from China and assembles them himself, with the aid of 2-3 other folks, in a garage. Specs are compelling, but they do not actually reflect reality.
And, frankly, stupid decisions get made. When I ordered my ZEV, I whimsically thought of picnics by the lake with my wife, and had a stereo mounted. Zehrbach thought it was a good plan to mount them on the footpads, because they were "solidly placed" there.
Is that the man you'd want to give 15k? If you can get at least the LRC 15 for 5k or less, and you don't mind routinely working on it, you'll be fine, I'd say that's a fair price point. It took me weeks, and I sold my ZEV for $1000. Less than the batteries were worth, just to get it out of my home.
Now, that is on me, I'm aware. But what led me to that is an extensive story, one that I pointed toward in above posts (and not in it's entirety at all--I'm really being quite restrained here).
I would have preferred a cruiser or scooter to picking up a Zero, honestly. I want a commuter ride. But the ZEV isn't safe, isn't well built, and is also expensive, plus you will receive some remarkably poor "customer service", judging from my experience.
If you don't want a Zero, and are looking at other options, you should probably wait. ZEV will not be a happy choice for you.
