That's a great car at a great price. The body shape is a little unusual to most Speedster and Spyder owners, but I am sure it goes like scoot, and it looks so well constructed.
You should contact https://www.rcnmag.com/, ReinCarNation magazine, and see if they would post an ad. They might even do an entire story on the car, and that might get you a good customer.
They did a story on my Intermeccanica S6 build, so give it a try.
