To build an electric car you need a good plan
I went about it the long way. I wanted an electric car for all the reasons you know about: cheap to run, low emissions and quiet. I priced them new which showed me these things were waaaay out of my budget range. I knew some people were building their own from an old car and I wanted to have a go. I could work most things out for myself but soon learned that, even I, need a decent set of electric car plans to make the project successful. Then I came across some ev conversion kit online and bought it. It’s been good. Lots of confirmation about what I thought had gone wrong. I’ll be on the road soon but you won’t hear me coming.
