As to the subject of dealerships closing, this has been going on for some years. There was a Land Rover / Range Rover dealership in our village and the owner told me that he’d had to surrender the franchise as JLR said that he’d have to invest over £1m on modernising the dealership in order to keep it.
In many parts of the country, car dealerships are vacating city and town centre locations in order to relocate to edge of town locations, where rents are lower, they have more space and customers can get to them easier. For example, many car dealerships in and around Bristol have closed and Cribbs Causeway (Jn 17 M5) now has large dealerships for almost every brand you can think of, from Ford to Aston Martin!
