A company planning to build a new off-road car has received a number of offers from European sites keen to produce the 4x4.
Ineos Automotive has started a search for a site, saying the UK remains its preferred location.
Ineos, which is hoping to produce at least 25,000 cars a year at the proposed facility, said it was willing to consider green field sites, former car plants and even existing production lines which can be re-configured for the new vehicle.
Tom Crotty, Ineos director of corporate affairs, said: "We've already had high level discussions with the UK Government as well as a lot of international interest.
"Whilst we would love this to be a British vehicle, this is a business venture and our hearts cannot be allowed to rule our heads."
Ineos intends to invest hundreds of millions of pounds in Projekt Grenadier - the code name for the venture.
The project is the brainchild of Ineos chairman Jim Ratcliffe, who was a fan of the original Land Rover Defender.
