CMC estimate is purely a SWAG. Years ago SOC tracked # signed up here by make - seems 75% were FF/CMC. Not sure if fair to include FiberFab (FF) figures in with CMC count but they sold under both name and locations) in '78-81. FF had ~20 models but Speedsters and maybe MGs/Avenger were best selling models. CMC produced Tiffany (Motors), Gazelle SSK, MGTD, Ford Vicy , Speedster (Classic, Calif, 359) plus a Cobra and Bugatti that I have never seen a single copy of (Barn finds in the making). Their buildin near Miami was 160,000 sq ft building (that's huge! Would be about about 570 garages). They produced cars for 17 years (1978-1995). Built primarily unfinished kits (except for Tiffany) with unfinished cars going for $8k each (at least for Speedsters). They also sold parts/options. They ended up with a $2M fine and $1M in inventory to be sold (was that book value or auction value?). In its prime CMC was doing $15,000,000- $20,000,000 US in revenue (is that a year?) and selling hundreds of kits a month (is that 300? 800?). 200 kits/month would be $1.6M/month so $19.2M/year! 200 kits/month say only 150 were Speedster is 1800 kits/year for just12 year (of their 17 year run) so 21,600 Speedsters produced (plus FF Speedsters - surely another 1-2K?). I'd put German DMs on 20k total build figure.
All figures confirmed using a 4th generation Cray XMP (aka iphone 8)!
