Diesels cars and other vehicles are poised to make a big comeback, according to the latest findings from J.D. Power and Associates. The survey said that one in four Americans would consider buying a diesel car; a year ago, that figure was more like one in 10. Clark remembers the diesel station wagon his family had when he was growing up. That automobile shook like crazy, had terrible acceleration and belched smoke and odor. But today's diesels are not like your daddy's diesel. Clark's driven some modern diesels throughout Europe and enjoyed great acceleration, quiet operation, good gas mileage and less pollution than a regular gas-engine car. So if you're looking for a car next year, diesel could be part of the picture. On a related note, J.D. Power also revealed stats about the reliability of vehicles after three years of ownership. Two brands tied for the top spot: the foreign-made Lexus and, somewhat surprisingly, the American-made Buick. In fact, several other American brands were toward the top of the tally, with Cadillac placing fourth and Mercury placing fifth. Meanwhile, Japanese standards like Honda and Toyota placed fifth and sixth, respectively. On the bottom of the heap were some foreign cars like Suzuki, Isuzu and Saab. But the single least reliable automobile -- based on how many problems were reported per 100 vehicles -- proved to be a Land Rover. Clark thinks it's interesting that some Japanese and European cars were selected as least reliable, while a lot of domestic rides are back on top. But perceptions take a long time to change, and people who grew up on foreign cars sometimes won't even consider a domestic vehicle.
