1980 saw the arrival of the Excalibur Series IV, the model of Excalibur that brought about the first real change in appearance of the marque. It was also the first Excalibur to have glass side windows and a trunk/boot integrated within the bodywork. The chassis, especially unchanged relative to the Series III's, was again stretched, this time by 13 inches. The styling had also evolved. It still undeniably evoked vintage Mercedes-Benz, but this time emulated the 500/540K series rather than the SS/SSK. This Series IV Phaeton utilizes a General Motors 305-cid V-8 engine and is also equipped with an Turbo-Hydramatic 400 automatic transmission. Although the performance continued to be decreased due to ever-increasing Federal requirements, the buying public seemed to readily accept this as they appeared more concerned with comfort and appointments than out-and-out performance dynamics. The Excalibur has four-wheel independent suspension with anti-roll bars front and rear, four-wheel disc brakes, posi-traction rear end, 30-gallon fuel tank and all-stainless dual exhaust system.

The brown with tan Excalibur Series IV Phaeton that is being offered has been with the same owner for the past 15 years. Our attending Auctions America Specialist has seen the Excalibur, and it appears to be completely original in presentation. He reports that the paint is nice, but oxidized; however, he is confident that a proper buffing would restore a nice shine to the surfaces. The seats are in good shape, with wear on the driver’s bolster. The door panels are also reported to be in good shape. The exterior chrome trim elements have a good appearance, but on close inspection, there are signs of pitting. The car is thought to have had moderate usage during its time. This Excalibur is equipped with power steering, brakes, windows, seats, top and antenna; Blaupunkt CD player, air conditioning, anti-theft tilt/telescopic steering wheel, cruise control, auto delay wipers, center-mounted driving light, four horns and tan soft-top. Additional features include chrome wire wheels with stainless spokes, new whitewall tires, VDO instrumentation, dual spotlights, dual side-mounted spares, faux external exhaust and integral trunk.
