I think MG would tell you the don't need to pick up any European engineering skills given they are currently knocking out the park with their BEV's and seem to be teaching the value orientated western brands a thing or two.
I think the advantage they obviously have is the huge manufacturing base/lead that China have for BEV's, they are making progress much faster than a lot of other companies/manufacturers in EU/NA but the stigma is still there, and I suppose to some extent that is reasonable, given that they only recently got out of the copying cars business.
I will say, I did enjoy the MG MG5 I have for a while, it was a good car for its price (when it was cheaper) and the new version looks a great deal improved. You are obviously going to get car ******* who'll **** off anything that isn't a Jaaaaag, or Audi etc. but mass market appeal cars will never meet their 'needs'.
EDIT: The new MG4 looks like a good contender for the less expensive CUV/crossover buyer -
