The Bitter CD is one of those rare grand tourers that rewards enthusiasts who enjoy something beyond the obvious European badges. Built in Germany from 1973 to 1979, the CD was the creation of former racing driver Erich Bitter, who transformed Opel Diplomat mechanicals into a low, elegant coupe with genuine luxury appeal. Under the long bonnet sat a 5.4 litre Chevrolet V8, paired with automatic transmission, giving the car smooth, effortless performance suited to high speed continental touring. Its styling, inspired by the Opel CD concept and shaped with help from Italian design influence, gave it a sleek profile that still looks distinctive today.

For owners and collectors, the Bitter CD is fascinating because it blends German engineering, American V8 torque and Italianate design character in one limited production package. Fewer than 400 were built, making replacement parts, maintenance planning and careful component selection especially important. At Automotive Superstore, enthusiasts maintaining classic and specialist vehicles like the Bitter CD can find quality service parts, oils, filters, ignition components, batteries, detailing products and workshop accessories to help keep prized cars road ready. An interesting piece of trivia is that Bitter targeted buyers who wanted Maserati or Ferrari style presence, but with more dependable Opel based running gear. That unusual formula gives the CD its cult status today: it is not merely a rebodied sedan, but a rare boutique grand tourer with a story as distinctive as its badge.
