I recently had a test drive in a MG3 - I was very impressed. Great spec, heated seats, heated steering wheel, 360 degree camera, comfortable and smooth drive. Insurance quote £572 fully comp. I can get the top spec on the road with metallic paint for less than £19k. It has a 3 speed gearbox but I never noticed it changing gear at all, it was very CVT like to drive. Looking at the MG3 forum there is no mention of anyone having a problem with the 12v battery. However I decided to wait to see what the forthcoming budget brings for the motorist. But now I think I will wait for my next new car until 2025 or even 2026. So much is changing in the new car market.
