I rather doubt anyone has done one.
While these days there is seemingly a preponderance of sat nav systems, and most people with them do make a list of places to visit, but I doubt many have more than a couple of dealers on them. Make a list of dealers and their postcodes from Miscellany and when you get your UK sat nav, just enter it in. The UK postcode which is used by sat navs here, is accurate to location within usually 100 yards and sometimes better.
Some of us though are luddites, and don't have a sat nav.
