1991 Mercedes-Benz 300SL-24 Roadster
VIN: WDBFA61E4MF021844
This 1991 Mercedes 300SL-24 was purchased out of Mesquite, Nevada, in March of 2023 with 140,500 miles on the odometer. It was driven from Mesquite to Poulsbo, Washington, and has seen a total of about 3,000 miles put on it by the current owner. Current mileage: 143,331. The car has been used recently as an occasional daily driver during warm months and has been shown at a few local car shows. The car presents well and is essentially rust-free.
First brought to the market in 1989, the 4th generation of the Mercedes-Benz SL class remains a favorite among collectors and drivers alike. This series of roadster was the last to carry Mercedes’ older nomenclature scheme that placed the “SL” range designation, which stands for Sportlich-Leicht (Sport Lightweight), after the number representing the engine displacement and as the last true “SL,” these cars are lately growing in popularity. The number “300” is in reference to the engine displacement, in this case the 3.0L DOHC I-6.
The M104 Mercedes 300 SL-24 engine is the 24-valve, 3-liter (2960-cc) Mercedes DOHC I-6 (228 hp (231 PS; 170 kW) at 6,300 rpm). The 1991 Mercedes-Benz 300 SL-24 had a reported top speed of 240 km/h (149 mph) and could accelerate from 0 to 100 km/h (62 mph) in 9.3 seconds when new, according to Wikipedia.
The 1991 Mercedes 300SL was the blast Mercedes with a standard (5-speed) transmission. This car, however, is a 5-speed automatic.
The previous owner reportedly had the car for 12 years. Work reportedly recently performed prior to the current owner’s purchase included:
new Bosch fuel pumps and filters
front struts
front brake rotors and pads
rebuilt hydraulics for the top
recent top
new windshield
rebuilt dash cluster
replaced ignition switch
tires reportedly had about 2000 miles on them and still have plenty of tread (but they are old and should be replaced)
Work done by the current owner in the past two years includes:
installed hard-wire trickle charger leads
new rear brake pads
new ignition switch
new headlight switch
replaced headlight relay
The power windows, mirrors, seats and hydraulic convertible top, and automatic roll bar all work properly. The heater system has been problematic since purchase (a used control module was purchased, but didn’t solve the problem – part included in sale). The air conditioning reportedly worked when the current owner bought the car, but he has never had it recharged. The auto-lock system doesn’t work properly. The electronic key fob was not included in the last purchase. The radio works poorly (speaker issues?) and only in warm temperatures. A second used radio head and an amplifier unit were both purchased, but didn’t solve the problem – parts are included in sale.
Last oil & filter change: July 4, 2023 @ 142,475 miles. Mobil 1 10W-40 full synthetic.
The car previously had a battery drain, and a battery cut-off switch was professionally installed by previous ownership. The drain was apparently resolved by installing either the new ignition or headlamp switches or the headlight relay. However, he has continued to use the battery kill switch whenever the car is parked for more than a few days.
