on 15 September and, according to a report in The Times on Saturday, 17 September, were close to a deal with SAIC under which they would manufacture the Rover 25 and Powertrain engines while SAIC would produce a stretched Rover 75. Nanjing Automobile Group was reported to be in exclusive negotiations with GB Sports Cars, a venture by former Rover managers, to re-establish MG production at Longbridge. In late October, key ex-workers received letters from Nanjing Automobile Corp offering 10 months' work dismantling plant at Longbridge for reassembly in China while talks with GB Sports Cars continued. However, after announcing that the UK government had not offered any substantial assistance in either grants or loans, Nanjing Automobile was also reported to have begun negotiations with at least two other potential partners, including "a wealthy San Francisco family", and, in early November, Nanjing committed to making every effort "to resume production [at Longbridge] at the beginning of 2007". In August 2008, more than three years after the facility had closed due to MG Rover's bankruptcy, assembly at Longbridge of a lightly revised MG TF roadster for the European market, from Chinese-built semi-knocked-down (SKD) kits, restarted. SAIC Motor merged with Nanjing Automobile in 2007, whilst nearly three-quarters of the massive Longbridge factory had been demolished and its land sold off - the old South Works is the only part of the plant which has survived. By 2011 MG Motor UK as it is now known started production of the first all new MG in 16 years, the MG6. In 2013 a new super-mini was added to the line up, the MG3. This was launched in summer 2013 and during 2014 helped in making MG Motor the fastest growing vehicle manufacturer within the UK. During the spring of 2015 a new MG6 was launched and plans for a new SUV were unveiled for the following year. Official reports The UK Government commissioned reports into the collapse of the company. The National Audit Office reported in March 2006 on the financial support provided to the company. It commended the DTI's contingency planning in 2004, but questioned whether the loan made in April 2005 achieved value for money. The DTI commissioned accountants BDO Stoy Hayward to report on the collapse of the company; this took four years to complete at a cost of £14.8 million. The firm issued its report to business minister Peter Mandelson
