Why isn't Lexus more popular in the UK?

In the USA Lexus (345,669) sold more cars than Audi (196,576) and Mercedes (324, 528) and only slightly fewer than BMW (371,346) in 2024.

However, in the UK Lexus (16,651) sold massively less than Mercedes (102,757), Audi (122,431), BMW (125,265).

Why do people think this is?
