As the Merlin was considered to be so important to the war effort, negotiations were started to establish an alternative production line outside the UK. Rolls-Royce staff visited North American automobile manufacturers to select one to build the Merlin in the U.S. or Canada. [[Henry Ford]] rescinded an initial offer to build the engine in the U.S. in July 1940, and the [[Packard Motor Car Company]] was selected to take on the [[United States dollar|$]]130,000,000 Merlin order (equivalent to ${{formatprice|{{Inflation|US|130,000,000|1940}}}} in {{Inflation-year|US}} dollars{{inflation-fn|US}}).<ref name=Time>[http://www.time.com/time/magazine/article/0,9171,795076,00.html ''Time Magazine'' (8 July 1940) – Business: Ford's Rolls-Royces.] {{webarchive|url=https://web.archive.org/web/20130721023935/http://www.time.com/time/magazine/article/0,9171,795076,00.html |date=21 July 2013 }} time.com.
