That would be a fun project but it would suck up a ton of time and money to do the conversion. We bought a used Nissan Leaf for our daughter a few years ago for $7500. Super cheap and very reliable transportation. It doesn't have a lot of range but you just jump in it and squirt around town. Biggest issue is that sometimes someone forgets to plug it in and then you're stuck. They charge up fine on a 110 wall plug but it takes time. If you have 220V in the garage then you can charge them a lot faster.
