About the Mercedes-Benz 250 S
The 250 S belonged to Mercedes-Benz's W108 sedan family, a long, elegant body with a 2.5 liter inline six.
Pre-Install Checklist
Seatbelt Planet does not include hardware, so check that your 250 S anchor bolts are present and sound before ordering.
Good to Know
Hardware is not included with this kit.
Lift latch buckles have the flip-up cover that suits the period look of a 1960s Mercedes interior.
The Black Wrinkle buckle option has a textured finish, while chrome matches the bright trim on the dashboard.
Fixed three-point belts adjust by hand and do not use a retractor reel.
Mercedes interiors of this era came in leather or MB-Tex vinyl in colors such as black, red, cognac and blue.
Seatbelt Planet sells rear belts for the 250 S separately.
The W108 sedans were long-wheelbase luxury cars with a tall glass area and plenty of rear legroom.
Mercedes-Benz was an early adopter of safety engineering, including crumple zones developed by Béla Barényi, which makes good belts fitting for these cars.
Owners who keep a 250 S original often want lift latch buckles because they suit the era better than modern push buttons.
Fixed three-point belts have a simple adjuster and no reel, which keeps the design compact.
The 250 S carburetor six was smooth and durable, and many of these sedans have covered huge distances.
Seatbelt Planet does not supply mounting bolts, so original Mercedes anchors should be cleaned and checked.
Cognac and black interiors are common in surviving 250 S sedans.
Order rear belts separately if you want the back seat covered too.
The 250 S pair suits owners who are rebuilding the front seats of their W108, since the belts can be fitted while the seats are out.
Choosing black wrinkle buckles gives the 250 S a understated look that blends with dark leather or MB-Tex.
Lift latch buckles are also popular with owners who want their Mercedes to look as it might have when dealer-equipped belts were fitted in the 1960s.
Mercedes 250 S sedans with original paint and interiors are increasingly treasured by collectors.
