Through his Delta Garages BMC dealership and business in Leighton Buzzard, Douglas Wilson-Spratt was able to put his ideas for special-body GT cars into production. In December 1962 the prototype WSM Sprite was unveiled at Silverstone, and following a great deal of interest shown by other drivers, a further twelve or more cars followed through until 1965. Several cars were exported to the USA and there are still at least five of the WSM Sprites in action today.

Sadly Douglas passed away on Tuesday morning 12th April. Although 'Anno Domini' - as Douglas termed it - had taken a toll on the speed of all his recent day-to-day activities, he remained stoically independent, razzing around in his recently acquired Smart car and still carrying out a schedule of meetings, lunches, catching up with old friends and making new ones. Douglas had plenty of plans for the future but his heart decided that running on too few cylinders for so long whilst trying to keep up with his busy timetable was an impossible mission.

Douglas’ son, Tony Wilson-Spratt, contacted all Douglas’ friends with this most touching eulogy: "Although I couldn’t take Dad to Brands Hatch on Saturday 9th April, his WSM's placed 1st, 3rd, 5th, 6th and 10th in practice for the HRDC Grand Touring Greats. I telephoned him and it took a while to get such a simple sentence out as I hadn’t realised how it would affect me so to tell him. I arrived back at 5.45am on Monday morning off the ferry and that evening we leafed through an album he'd started with recent pictures of the WSM cars and occasions. He reminded me he was driving to France next week for a wedding and champagne tour, and that the Jodel was nearly finished. I fixed his television and said goodnight and that I'd see him tomorrow, when he would give me the guest list for his 90th planned on 16th June. I'm afraid this morning he collapsed, in company, and was taken to hospital where they were unable to revive him. The heart that's been operating for so many years on two or three cylinders finally cried 'enough'. I miss him already".
