If GM managed to build the EV1 with great specs and at a reasonable price why has no one been able to do it again?

I been interested in buying an electric car but I have failed to find cost effective alternatives on the internet that meet my needs. I’ve seen lots of concepts but very few actual production models.

Do-it-yourself conversion kits do not seduce me at all as most of them are not very well integrated. I wonder for something that is more commercial and that I am able to buy easily, not just for lease.

I saw the specifications of the EV1, and they are very good, I would buy it today at the very same price it was sold then. And that is technology of 1996, 16 years from now! I am sure there have been some advances in electric motors and batteries by now.
I know there is the auto industry, and the oil industry and that they are buying the designs, but I refuse to believe that there has not been one single person in the whole world that has produced a good EV and did not sold the design to any of the big industries
