As you may recall, China's SAIC purchased the assets of MG Rover in 2005, but BMW sold the rights to the Rover name to Ford to protect the Land Rover brand. SAIC now produces Rovers under the Roewe nameplate in China.
The Lanchester nameplate -- which is also linked to Jaguar -- hasn't been used since 1956.
It's unlikely that Tata will produce any vehicles under the British nameplates, but it could license their use to alleviate some of the $2.3 billion in loans it just took on.
