Indian car maker Tata Motors is rumoured to be considering a bid for Jaguar.The firm is said to have signed a confidentiality agreement with Ford, and is looking into Jaguar's accounts.Tata Motors – part of the massive business empire founded run by businessman Ratan Tata – is best known in the UK for producing the ill-fated CityRover supermini.It is India's largest car maker. It was established in 1945, but did not start producing its own cars until 1954. There are currently around four million Tatas on India's roads.Along with passenger cars, Tata produces many commercial vehicles. In 2004 it acquired Daewoo Commercial Vehicles, and in 2005 it bought a stake in Spanish coach maker Hispano Carrocera. Tata also produces vehicles and engines in conjunction with Fiat, including a Fiat-badged Tata pick-up made under licence in Argentina.While Jaguar might not seem to fit with Tata's current cart making line-up (the Indian firm is currently working on a £1500 car, expected to be launched in the next 12 months), Tata Group is known for big takeovers. Earlier in 2007 Tata Steel bought the British steel maker Corus for almost £7 billion.Ford has said that tomorrow (19 July) is the deadline for offers for both Jaguar and Land Rover.
