The (very) few websites I could find this car on all called it "Оксалия", which the apparently poor translation programs I tried all showed as "Oxal". I tried one more and it gave me "Oksaliâ", so I'll go with that, maybe even Americanizing it to "Oxalia".
It's really quite a neat piece of work - there are a few more photos of it on the internet, and the builder did a very creditable job. One of the web sites makes it sound like its body is made of fiberglass, not steel. Do you know more about it?
