In my opinion the MG6 was penned still under Uk ownership, and as the factory still had ties to chassis from Honda (ZS ZR) it seems very strange that when you look at the current Civic (not the euro dross we have but the real civic / integra) it still uses the same chassis as the ZS which is a honda.
At MG live a hybrid civic was parked and looks almost identical to the MG 6. Ok the chinese have had copy bmw parts made for the running gear which is ZT wheels/ brakes suspension. But then again a BMW have invested in cars being made in China they are probably made under license.
