Use craigslist - there are still quite a few CRXs out there, but most are riced out and are at least $2k. You could get lucky, but you need to look at craigslist for your surrounding area (I suggest using crazedlist dot com or similar service) oh about every 3 hours to make sure someone doesn't snatch up the one you want before you see the ad. I've been searching on CL for a CRX for an EV conversion for a while now, and it's hard to come by a CRX in even the worst condition for under $500. I would suggest getting a geo metro or similar variant because ricers aren't after them, they are more pervasive/easier to come by, can afford similar if not better mileage than a CRX, and are typically less expensive. It may also be easier to get cheap and/or used parts for a metro/variant. I know the feeling though - that's a stylish little car and I want one too, but I won't have to worry about finding sought-after ICE components once I convert it. Good luck
