It's a subsidiary of Street Rod Engineering, see the first link on their web page. SRE has been in business for many years so if you expand your question to include that company you'll probably get more feedback on their reliability as a company. I don't know anyone that has bought their glass car yet.

Now for personal opinion. Model A sedan bodies are still plentiful, and when compared to the cost of the new glass piece are still reasonably priced. The current gasoline price has stopped the rapid increases in price that we've seen the past 4 years or so. If the gasoline price stays up the number of people playing this game will diminish, lowering demand, thus lowering prices. This will have a twofold effect. BTW, I'm not one of those "I hate fiberglass cars" guys, I've owned a few myself. But going forward, if gasoline prices stay high, or get even higher, the hobby will shrink to the "hard core" hobbyists which will hurt the fiberglass car market as these "hard core" types will have a vast market of cars to choose from and will tend toward steel. If you can afford to not be concerned about future ability to sell the car, even at a big loss, then none of that matters, buy what you like and live with the decision. If you're not in a hot hurry, some real bargains may be just around the corner. It happened in the '70s.........many of us could have bought rods, muscle cars, and all manner of cars that were selling for "give-a-way" prices. History often repeats.
