At the beginning of the 1970's, the UK was exporting 36% more passenger cars than it was importing. To put that into time context, the UK joined the EU in 1973. By 1977 it was neutral and thereafter it has been in the minus region.

Land Rover Discovery Top Nations : 2022

The current Discovery is a top draw product that doesn't sell in the numbers it deserves to. The UK is the primary market with 30% of sales. In some European countries like Ireland, it is very popular as a commercial vehicle with just two seats (see picture below).
What may put off some buyers is it is so good off road that there has to be some compromise when on tarmac. It has a breadth of talent that go beyond what most users need, in some respects an overkill. The sort of thing I don't need but somewhere in my subconscious I'd like to own. Not to satisfy a materialistic craving but a fascination with what it can do.
The data below is from various sources, not from JLR and sources can vary. One or two top nations may be missing.
Range Rover Velar Top Nations : 2022
Rolls Royce Global Sales : 2022

Rolls Royce passed 4,000 deliveries for the first time in 2014 and I thought that was probably as high as it would get. For a few years, it seemed so then a sudden upturn and 5,000 was reached in 2019. That was because of the Cullinan SUV and I hadn't allowed for such a model when making my prediction.
The Cullinan has passed the 50% mark for the company and this sort of vehicle is an essential part of any car maker's range...except Mclaren and I'm thinking they will come around eventually. It would be ultimately suicidal not to.
Looking at the picture above, they certainly have quite a presence. The problem is it's too long for my garage. Shame about that. But as the old saying goes, if it doesn't fit in the garage then you can't afford one.
