During the 91-95 run in house Monster Motorsports approx 100.
We started selling kits to "dealers" in 93 and then to individuals later that year. It is hard to say how many independent but likely an additional 100 kits. Likely another 100 kits since 95 supplied by Martin. By early 90's standards they were a well balanced, formidable little machine with the bracing and brake upgrades. With the price of used 5.0 and Miata's you could easily build one for 10K
