Saying the car is taking too long to come to market is opinion, not fact. You are also making assumptions regarding the 1.5 in that the engines in the China cars will be carried straight over to the Euro cars. Would it not be a fairer assumption to assume that in the 18 months or so between the car being launched in China and Europe that MG might be making significant changes to the powertrains to ensure the car is up to Euro class standards when it is launched?
Do the wider public (in Britain?) need to know of the car's existence when they won't be able to buy one for months?
