Because you didn't want the smell and warm-up time to save a measley six cents a gallon.
Well, I did park next to a very noisy Ford 250 diesel pickup today. But I remember test driving an OLDS diesel 88 or 98 that seemed as quiet and smooth as a gas one.The bank wouldn't loan on diesels period. And GM really blew it with reliability problems on those cars. I know a fellow who loves to mention the 12 gallons of diesel he puts in his VW every other week. His fuel mileage is three times mine.(OK,so mine is a K1500 v8350)
