I remember Mario Deliotti when he had the Alfa Romeo Car Dealership in Sparkhill and what a nice chap he was, a former motor cycle grand prix racer and he had been Bruno Giacomelli's race engineer when at Alfa works Team!
He ran the business to finance his racing team with the cars being made at workshops in Walsall and I remember having seen the cars being built there and also finishing touches to the livery and decals for sponsorship at his dealership on the Stratford Road. He was a true motor racing enthusiast turned F1 Team Owner just the same as Frank Williams started back then something you can't do today! Frank became a personal friend of his and he took an interest in the Team and on one occasion when he saw one of the cars which had been prepared made comment that "it was a neat little package" and that "it might go well with a good engine" and this is where the engine came from? A Customer Cosworth DFV from Williams on loan and test replacing the Matra V12 engine because it was shorter! It went better and when in the hands of a competent driver its improvement in handling was immediately obvious and the car went quicker and then twin four pot brake calipers had to be installed on the front wheels to stop the car!! The car became a serious contender and many young aspiring drivers got to debue the car in anger including an experienced Geoff Lees who was chosen over the then young Nigel Mansell to compete at the British Grand Prix at Silverstone.
When Mario closed the Dealership the Team continued as a Racing Team hence the name Mario Deliotti Racing and they moved to Ireland and then Mario passed away and the Team moved onto Switzerland competing as Mario Deliotti Racing (Switzerland). The Team is in America and the brand lives on and was in the hands of privateers Bob Moshinski and Dave Ferrari competing in the US Masters Series with the same cars and the same name somewhere in New England and they have workshops maintaining Ensigns and other racing cars of the same period.
