It was made too expensive 30 years ago!
I have a friend down in Yorkshire who's lucky enough to own an old Silver Cloud III. Recently he told me it was cheaper to drive the Rolls to London and back AND spend the night in a half decent B&B than it was to get two retune tickets for him and his wife....
As for the service itself! To (just!) get to the college in time for a 9am class I'd need to be out my front door by 6:55. Plus there's the miserable walk from Central to Stow... If I finish at 5pm I won't see the house again 'till 7:30pm....
For a 9am class I generally crawl into my car at 8am and am at the front door of the college by 8:45. Time for a coffee.... No walk in the rain, warm, comfortable, goes when I want it to go...
I usually make it home well before six. And the tenner's worth of petrol I use beats the nearly £13 full train fair by some way....
