1965 Buick Riviera--Remember when he buys it, he asks the salesman if the clamshell headlight's work.
Changes for 1965 included the introduction of the Gran Sport option, which included the dual-quad Super Wildcat 425 V8, a numerically higher 3.42 axle ratio, dual exhausts, and stiffer, heavy-duty suspension. The 401 (6.5 L)V8 returned as the standard Riviera engine and the Super Turbine 400 transmission now had a variable pitch torque converter like the old Twin Turbine Dynaflow had two years before. Externally, the headlamps were concealed behind clamshell doors in the leading edges of each fender, as in the original design. Further back, the non-functional side scoops between the doors and rear wheel arches were removed, and the taillights were moved from the body into the rear bumper. A vinyl roof became available as an option, initially offered only in black.

Dalton's favorite auto is his Mercedes 560 SEC Coupe. However, he puts it into storage when working, buying instead a junk car from the local used car dealer, with plenty of spare tires in the trunk.
