I’m not sure about this. If they changed the shape, which they did. Then until you try to fit them you have no way of knowing they will fit.
Prior to realising, that comprehensive support was non existent for the ZS Hybrid + I ordered mine, and at the same time I ordered a set of mats for it, (£80). They were in the car when I took delivery, and appear to fit ok.
To be honest, I now suspect that they are actually intended to fit the previous ZS model, but as the ZS, and the Hybrid + are similar, and although the Hybrid is a bit bigger, they fit.
I also tried to get some mud flaps for my Hybrid + but they are only available for the old ZS, and I’m refraining from purchasing, as I don’t want to have to drill holes in my new car to make them fit.
It’s about time MG UK got their act together.
