These cars are Hot!
Not only hot they were designed by Porsche. Below is a Wiki excerpt.
Between 1991 and 1995, Mercedes Benz sold a sport version of the W124, the Mercedes Benz 500 E, created in close cooperation with Porsche. Each 500 E was hand-built by Porsche, being transported back and forth between the Mercedes plant and Porsche’s Rossle-Bau plant in Zuffenhausen during assembly — taking a full 18 days to complete each model. Design began in 1989 and into 1991. Between 1992 and 1994, Mercedes/Porsche built a total of 10,359 500 E’s (1990 — 46 units; 1991 — 2,566 units; 1992 — 4,416 units; 1993 — 1,596 units; 1994 — 1,735 units). Called ‘500 E’ through model year 1993, for model year 1994 it was face-lifted along with the rest of the range and renamed to ‘E 500’.Of these, 1505 of the “super” sports sedans were imported into the USA between 1992–1994, or roughly 500 cars per year of importation.
The 500 E had a naturally aspirated dual camshaft 32-valve 4,973 cm3 V8 engine producing 326 hp (240 kW) and 354 ft·lbf (480 N·m)  with the engine being derived from the 500 SL (R129) roadster. Sports car braking performance also came from SL components: front SL 500 300 mm disks with 4-piston calipers came installed on the 1992 and early 1993 cars. The later 1993, and all 1994 cars came with the upgraded 320 mm set taken from the 600 SL. Rear brakes on all years were 278 mm brakes from the 500 SL. In the USA, the 500 E came fully-loaded, with the only options available to the buyer being a dealer-installed CD changer and an integrated cellular telephone. The 500 E was only available as a four-seater in left hand drive, with the four leather seats supplied by Recaro (the fronts heated).
Called the “Wolf in Sheep’s Clothing” by the press, performance tests of the day yielded impressive results: 0–100 km/h (0–62 mph) times of 5.5 to 6.0 seconds and acceleration through the quarter-mile (0.4 km) in 14.1 seconds at 163 km/h (101 mph). The top speed was redline limited at 6,000 rpm to 250 km/h (~155 mph). It was rated at 16.8 L/100 km (14 mpg) in the city and 13.8 L/100 km (17 mpg) on the highway.
With its aggressive stance: 1.5 inches wider track, 0.9 inch lower profile, flared fenders, side skirts, front air-dam and wide tires, the 500 E is easily distinguished from its lesser brethren. Because of its look, limited numbers, hand-built construction, and unique pedigree, the 500 E is already considered a “classic”, even within Mercedes Benz.
