For as long as I can remember, this showroom has been selling secondhand luxury cars on the Uxbridge Road in Hanwell.
[Update] A recent revelation via the Twitter account @EalingCinema is that the building was once a cinema called the Coronation Hall Picture Palace, a rather grandiose name, I feel. Here it is on a map from 1914, and you can also see the Grand Electric Theatre (latterly the Tudor) on Cherington Road.
I have also found the listings for them in Kelly’s Directory of Middlesex, 1914.
