China’s Shanghai Automotive (SAIC) hopes to begin producing the MG TF roadster in Nanjing in May and at its plant in Longbridge, UK, within three months of that date, a senior executive said yesterday.

But SAIC admitted the car’s long-awaited relaunch could be delayed again as it grapples with quality issues and rebuilds tooling bought in 2005 from bankrupt MG Rover and shipped to China by Nanjing Automobile (NAC), with which SAIC merged in December.
