Cadillac is the second oldest American automobile marque behind Buick, formed from the remains of the Henry Ford Company. Its first cars – the Runabout and Tonneau were well known for being more reliable than its competitors with the brand itself known for precision engineering and fine luxury which still applies to the present. Postwar Cadillacs were symbolic for their style, especially the tail fins on the Eldorado and was the first manufacturer to introduce air conditioning in 1964. In present times, Cadillac has resisted reviving old models and instead focused on all-new models, mainly sedans competing against those in Germany and Japan. Cadillac competes in the high performance sedan market with the CTS-V, which previously held the record for the fastest car in its class on the Nürburgring.
