It's definitely no secret that automotive manufacturers do trade technology and equipment however.
The suspension is designed in-house by the Cadillac Division of GM (which just moved out of Detroit to New York) and manufactured by BWI Group, formerly part of Delphi Automotive Systems, in the USA. Delphi is a massive global parts-making operation headquartered in the UK, that had been spun out of GM then went through bankruptcy reorganization prior to the 2009 GM bankruptcy. The Suspension Components Group was then resold in 2009 to a Chinese company, BeijingWest Intl. (BWI Group).
Various parts of the North American Delphi operations have been sold off to other USA manufacturing companies since 2009 as Delphi rationalizes its operations. General Motors, once a truly global, fully vertically integrated company, is now a shadow of its former self - essentially a design and assembly company which sources parts from the operations that now own its former parts factories.
Cadillac and Corvette share performance group research and design facilities. I believe eventually the two brands will separate from the more pedestrian Chevrolet and Buick brands to establish a more BMW-like identity.
AFAIK there is no current general technology sharing with Mercedes but at one time they jointly developed fuel injection systems. Daimler briefly owned Chrysler Corp (now owned by Fiat).
Oddly, my wife just bought a Mini Hardtop, which is a BMW, so you just can't tell any more.
