I think they were made by someone in Texas. I’d find out about getting spare parts, spindles and such. That will determine the value. If parts are available and it’s ready to fire up and hit the track I might go $1200. If it needs a little work to hit the track maybe $800. If it needs work and you can’t find parts, maybe $250. There are a lot of ifs. My son-in-law bought an Ultramax Proforce with a Predator engine that needed about $250 to get it on the track. He paid $250, so he’s got 5 in it race ready. I paid $1200 for a Seraph with an L0206, race ready with minimal wrenching. Food for thought.
