Basic information and history

Mercedes-Benz W124 in 300E 4MATIC specification from 1991 combines the classic W124 architecture with Stuttgart’s first-generation all-wheel drive. The model is built around the M103, an inline-six with KE-Jetronic and robust components, and the 4MATIC system uses electrohydraulically controlled multi-plate clutches that engage the front axle and differential locks as required. This was a technical milestone in the segment and provides secure traction without compromising the W124’s well-known road manners.

This example is a 1991 model year 300E 4MATIC with automatic transmission. The odometer is stated at 276,000 kilometers. The paint is said to be in good condition and was previously refurbished by a former owner. The body has a small rust blister at the upper edge of the rear window. The glass is free from stone chips and all panes are etched with the registration number. Chrome, trim, light lenses and badges are reported to be without remarks. The interior is described as complete, with damage to the driver’s seat backrest at the entry area and cracks in the wood on the center console. The radio is missing, but four speakers are fitted with a separate balance control on the center panel. There are no power windows; the electrically adjustable exterior mirror works. Old inspection reports are included.

Equipment and options

• 4MATIC all-wheel drive
• Automatic transmission
• M103 inline-six with KE-Jetronic
• Power-adjustable exterior mirror
• Climate control
• Four speakers with balance control on the center panel
• Nokian Hakkapeliitta M+S 195/65 R15
• Mercedes 15-hole original wheels, often called “manhole cover” wheels
• Etched windows with registration number

Modifications and improvements: The car is said to be largely original. The paint has been refurbished by a previous owner. Under the current owner the fuel and pressure accumulators have been replaced and the KE-Jetronic main unit overhauled. All driveline oils were changed at a previous service. The climate system has been charged with an alternative refrigerant with lower environmental impact.

Condition

Body and exterior: The paint is described as being in good condition after an earlier paint refurbishment. A small rust blister is present at the upper edge of the rear window. Windows without visible stone chips and etched registration numbers. Chrome, trim, light lenses and badges without remarks according to the seller.

Interior: The cabin is complete. The driver’s seat backrest has damage at the entry area. The wood inlays on the center console have cracks and crazing. Headliner without remark. Controls and buttons function; the radio is missing but four speakers are present with balance control. No power windows are fitted; the power-adjustable exterior mirror works. The climate system does not cool as it should due to a leak; an alternative refrigerant has been used.

Tyres and wheels: Nokian Hakkapeliitta M+S 195/65 R15 with approximately 5–7 mm tread depth. 15-hole original wheels with scratches and signs of curb contact on the outer rim lip.

Mechanics and function: The engine runs as it should and is said to be well maintained, with ancillaries in order. The transmission shifts smoothly and the driveline operates correctly, with fresh, specification-grade oils in all units. The brakes are assessed to be in good condition, with the note that the car cannot be tested in the usual way on a brake dyno due to 4MATIC. The parking brake is somewhat weak but within tolerance at the roadworthiness inspection.

Summary

A 1991 Mercedes-Benz 300E 4MATIC that combines the W124 platform’s well-known build quality with early 4MATIC technology. The exterior is tidy after an older paint refurbishment, with a minor rust indication at the rear window. The interior is complete with a note on the driver’s seat and cracks in the wood trim. The mechanics appear well cared for, with a recently overhauled KE-Jetronic, renewed accumulators and serviced driveline. The climate system needs attention for full function, and the radio is missing, but four speakers are present. For the enthusiast seeking an honest W124 300E 4MATIC in largely original specification and with documented owner efforts on servicing and the fuel system, this is an interesting car to follow on Bidders Highway.
