Not sure what "IMC" is.
Frank Resiner formed Intermeccanica in Europe in the 50s, and was a coach builder. Painting with a very brad brush, what he built in Europe were sportscar bodies using American car running gear.
In the '70s, he immigrated to the USA (Los Angeles, California) with his family, and gained a partner building 356 Speedster (not Convertible D) replica cars and kits. Frank sold his half of the business and moved his family to Vancouver, BC Canada, the partner sold the Speedster molds, etc. to CMC.
Frank built turnkey replica 356 Convertible Ds in Canada until his not-to-compete agreement timed out, when they started building Speedsters again as well. Frank's son Henry eventually took over the family business, and ran it as a stand-alone business for another 20+ years.
Several years ago, Intermeccanica was acquired by a venture capital funded start-up, with the purpose of building electric cars. The company is now a publicly traded company called Meccanica and is listed on the NASDAQ. Production of the electric cars will be in China, with the R&D and production work overseen by Henry Reisner. He makes a LOT of trips to China now.
Speedster and Roadster construction has continued in Vancouver, but is no longer the main thrust of the business-- bringing the electric car (the Solo) to production is a matter of survival now. Last spring, Henry made the announcement (in his newsletter) that Intermeccanica would end ICE car production and that future replicas built by them would be all electric. Apparently, later in 2019 a new CEO reversed that decision, and production of ICE replicas is ongoing, although no formal announcement from Henry, Intermeccanica, or the parent company (Meccanica) has been forthcoming.
You may have difficulty reaching anybody at Intermeccanica because:
- What you have was built 45 years and 3 companies ago
- Henry and staff are really, really focused on trying to bring the Solo to production
I'm sorry I can't be of more assistance, but this is the landscape now.
