What vehicle produced by General Motors from 1962 to 2002 did testers feel was a more roadworthy car as compared to the Ford Thunderbird?
Ford Thunderbird (fourth generation) The fourth generation of the Ford Thunderbird is a large personal luxury car produced by Ford for the 1964 to 1966 model years. This generation of the Thunderbird was restyled in favor of a more squared-off, "formal" look. The Thunderbird's sporty image had by that time become only that: the standard 390-cubic-inch 300 bhp V8 engine needed nearly 11 seconds to push the heavy T-bird to 60 mph (96 km/h). The softly sprung suspension allowed considerable body lean, wallow, and float on curves and bumps. Contemporary testers felt that the Buick Riviera and Pontiac Grand Prix were substantially more roadworthy cars, but the Thunderbird retained its leading market share.
Mercury Turnpike Cruiser The Mercury Turnpike Cruiser is a full-size automobile that was the flagship model of the Mercury division of Ford Motor Company for the 1957 and 1958 model years.

In 1957, a two-door convertible was also produced, serving as the pace car for the Indianapolis 500 of that year.
