The red convertible driven by Don Adams in the opening credits for the first two seasons is a 1965 Sunbeam Tiger Mark I, which came standard with a Ford 260 V8 engine. The car was used in several episodes throughout the first four seasons, though sometimes substituted by a very similar-looking Sunbeam Alpine with Tiger badging. A Volkswagen Karmann Ghia was used in the opening credits for the third and fourth seasons but never used in any episode. For the fifth season, the show featured a 1969 Opel GT used in the opening credits as well as the episodes for that season. Only used in the pilot episode was an early-'60s Ferrari 250 GT cabriolet.
