Although this a questioned which has been the center of debate for some time I have spent countless hours researching this subject and have come to the conclusion that the 1989 Ford festiva is indeed the longest production car ever produced in the U.S.A.
1974-'76 Cadillac Fleetwood was the longest in length.
The longest mass-produced production car was the 1974-'76 Cadillac Fleetwood Seventy-Five (available in 9-passenger and limousine series). They were 252.2" in length. This was just over 21 feet. Wheelbase was 151.5". There were 6 Bugatti Royales built in the 1920s which were over 22 feet in length.
The Maybach 62 is currently the largest production car at 242.7inches. The longest production vehicle is the F350 4dr/long bed at 263inches. Limo's are the longest non production.

The shortest production car in history was the 1962 to 1965 Peel P50. It was only 52.8 inches in total length.

The Chevrolet Suburban, is the longest running model name in US automotive history.
The longest car in the world is 30.5 Meters it's a limosine, and has such luxeries as a swiming pool, bar, and even helicopter landing pad on the back!
If we limit answers to production cars rather than custom built limousines, the longest is probably a 1975 Cadillac Fleetwood 75 at 6,426mm (253"). The longest wheelbase, as opposed to overall body length, could be a Mercedes Benz 600 at 3,900mm (154").
The Production Budget for The Longest Yard was $82,000,000.
The longest length would be the hypotenuse. You can use SOHCAHTOA to find the length.
