Apr 20, 2019

The Aging Process and Maintenance

As proud owners of a 1985 model W123 or W126 diesel, it is important to acknowledge the challenges that come with owning a vintage vehicle. These iconic Mercedes-Benz models have undoubtedly stood the test of time but require meticulous maintenance to ensure their longevity.

The aging process can take a toll on both the exterior and interior components of these classic cars. Rust, paint fading, and upholstery wear are common issues that need attention. Regular inspections, cleaning, and restoration efforts are essential to preserve their original charm.

Availability of Parts

One of the major challenges faced by owners of these vintage cars is the limited availability of parts. Due to their age, some parts may no longer be manufactured or easily accessible. This can make repairs and replacements more challenging and time-consuming.

Fortunately, Grafco Electric understands this concern and specializes in sourcing and providing rare parts for these specific models. We work closely with trusted suppliers to ensure our customers can maintain their prized vehicles without compromise.

Fuel Efficiency and Emissions

Another aspect that owners often grapple with is fuel efficiency and emissions. While these diesel models were known for their efficiency back in the day, they might not match the standards of modern vehicles. Issues like poor mileage and increased emissions can arise, resulting in higher fuel costs and environmental concerns.

At Grafco Electric, we offer expert advice and solutions to enhance the fuel efficiency of your W123 or W126 diesel.

Electrical System Upgrade

One of the challenges specific to these model years is the outdated electrical system. With technological advancements over the years, the original electrical components may not meet the requirements of modern accessories and electrical devices. This can limit the functionality and convenience of your vehicle.
