Was the Crown Victoria right hand drive too?
There were some right hand drive Subarus sold here for postal vehicles a few years back.
I test drove a diplomats' right hand drive Ford Fiesta many years ago, a late 80s model. I had few problems with the shift or pedals but after a few minutes I realized that I was trying to drive in my lane but the passenger half of the car was in the oncoming lane!
I think if I visit England, I'll try the train or bus first.

Happy Motoring, Mark
