In the 1980 model year, a full line of automobiles on the X-body platform, anchored by the Chevrolet Citation, was launched. Again, these cars were all quite popular in their respective segments for the first couple of years, but brake problems, and other defects, ended up giving them, known to the public as "X-Cars", such a bad reputation that the 1985 model year was their last. The J-body cars, namely the Chevrolet Cavalier and Pontiac Sunbird, took their place, starting with the 1982 model year. Quality was better, but still not exemplary, although good enough to survive through three generations to the 2005 model year. They were produced in a much-improved Lordstown Assembly plant, as were their replacements, the Chevrolet Cobalt and Pontiac Pursuit/G5.
