It has been the case for years that manufacturers like Honda, BMW and I assume others, require dealerships to be lit and decorated in corporate colours, to the satisfaction of said manufacturer. These days, the dealers that can afford or justify that huge expense are few and far between.
Down here in the South West we have very few big dealers; Fowlers in Bristol, Riders in Bridgwater / Bristol and others in Taunton and Exeter. However, in between all those big showrooms are a whole network of little independent dealers some specialists in a brand, MZ or BMW, some selling Chinese and Indian brand bikes / scooters, all of them with good s/h stock that constantly turns over.
I don't know what impact these little dealers / workshops have on national sales figures, very little I suspect, but they seem to be the ones making a steady living out of sales, service and MOT's.
Long may they continue.
