Whether you agree or disagree with the new products of a particular company, they are only there to make a profit and that means supplying whatever the market demands at that time and in the foreseeable future - be it diesels, SUV's, EV's, etc.
Considering where the current MG's started from, they are showing a sensible sales increase year-on-year with the new ZS, something that didn't really happen with the original MG6 & Magnette.
The buying public currently seem to want small to medium SUV's - Juke, Ecosport, Crossland X, etc. so as much as MG were never known for this type of vehicle, they are at least building what people want. Maybe if the original MG Rover had done this, history would now be quite different
As for JLR, farmers buying a new Defender every 10 years will never give the profits seen from the current line-up sold on 3 year PCP's.
