Description:
Selling my classic 1988 Mercedes-Benz 420SEL (W126 long-wheelbase). This is a solid, luxurious cruiser powered by the legendary 4.2L V8 engine. It has 200,548 miles, a clean title, and runs and drives straight and smooth. Priced low at $3,000 for a quick sale.
Perfect project for a Mercedes enthusiast or a classic daily driver.
Recent Maintenance & New Parts
The typical, expensive W126 problem areas have already been addressed with high-quality parts:
• Front lower ball joints replaced and serviced at John & Holger (critical for proper handling and safety)
• Twin Pump Fuel Delivery Overhaul Kit from MercedesSource installed. This overhaul includes:
• 2 brand new Bosch fuel pumps
• New German fuel filter
• New accumulator
• Heater Monovalve Repair Kit installed (proper heat control in the cabin)
Included Spare Parts
I am including extra parts with the sale of the vehicle (including several rare electronic modules, used spares, and brand new components from AutohausAZ to help troubleshoot the minor quirks):
• Spare EZL Ignition Control Module (highly valuable and hard-to-find spare)
• Used Bosch EHA (Electro-Hydraulic Actuator) (crucial fuel system spare)
• Used Fuel Pump Relay
• Brand new AC Expansion Valve (ACM Germany, sourced from AutohausAZ—perfect for sorting the AC)
• Brand new Overload Protection (OVP) Relay
• Brand new Air Flow Meter / Potentiometer (New in Box—included to address the intermittent acceleration hesitation noted below)
• Complete set of 4 chrome wheel arch covers
• 3 sets of used Bendix front brake calipers
• 1 set of used OEM Mercedes rear brake calipers
• Rear windscreen (comes with a brand new rubber seal)
• Rear driver-side window slider repair kit (included to fix the window issue)
• 70-Amp (70A) Alternator
• Brand new Power Antenna (New in Box)
• Spare rearview mirrors
Vehicle Condition
• Mechanical: Engine starts up and the transmission shifts smoothly. There is an intermittent hesitation when accelerating, which is a known symptom of the Air Flow Meter / Potentiometer. I bought a brand new replacement part for it, which is included in the sale but hasn't been installed yet. Please note the AC does not blow cold and will need troubleshooting (brand new German expansion valve is included).
• Electrical / Interior Features: Classic Palomino Leather interior. The front windows and passenger-side rear window work properly. The rear driver-side window does not go down (repair kit is included). The moonroof tilts up properly but doesn't go back down fully flush when closing, so the mechanism will need to be looked at.
• Exterior / Glass: Classic black paint. Please note the front windshield has a crack and will eventually need to be replaced. There is also some rust starting on the wheel arches and the A-pillars, which is typical for these chassis over time. The rest of the body is straight and solid.
• Tires & Brakes: Tires have plenty of tread left. Brakes feel firm and responsive.
Separate Add-on Opportunity (Negotiable)
• Bridgestone Blizzak WS90 winter tires mounted on rims. These are perfect for Michigan winters but are not included in the base $3,000 vehicle price. I am happy to negotiate a package deal to add these if you want them.
Serious inquiries only. Priced to move quickly, so please no lowball offers. Clean title in hand, ready for a new owner. Located in Warren, Michigan for viewing. Cash or certified bank draft only.
