A limited edition version of the Longbridge-built MG TF sports car will be launched by Nanjing Automobile next year.
But the reintroduction of the LE 500 - so named because only 500 will be built - and the conventional TFs will be delayed after the Chinese carmaker missed its end of the year target to relaunch the brand in the UK.
Logistical problems of bringing some components over from China have meant new components have had to be sourced, necessitating new tests.
Among the problems have been windscreens which smashed while in transit. Eleanor de la Haye, spokeswoman for NAC - MG said the launch had been delayed as a result of the need for further testing of the cars.
"We are having a very comprehensive testing programme. But there have been logistical issues and we have been following what has been happening in China.
"The car isn't going to launch in China until October 16, and doesn't make sense to launch a convertible sports car in the UK at that time of the year.
"It is not much of a delay and people will be able to see the cars in showrooms from February and get the cars from March."
Prices for the car are currently being worked out.
"It will be competitively priced," said Mrs de la Haye. "I am sure people will be pleasantly surprised."
