Hamshaw's was a very big deal in Leicester, occupied three sites and it's great that the Parker Drive site has been preserved (albeit full of bathrooms and toilets!!), and as many dealerships were back then it's a great looking building (maybe listed?). They started as a coachbuilder originally and became a very big Morris distributor, big showrooms, rolling road, light and heavy parts stockists, paint shops, service, they did the lot! They produced a lovely brochure at one time giving a potted history of the firm, and some nice pictures of Minis in the premises, one of some Mini vans being sprayed and signwritten, another with a Cooper S at the front of the showroom.
