This 1989 Mercedes 300SL has been in the long term family ownership and was brought to us so it could be restored with longevity in mind. Our appraisal of the vehicles current condition formed the basis for a work schedule which would result in restoring it to pristine condition.
A common and well known problem with R107 models is water ingress into the front footwells coming through the bulkhead/ heater plenum chamber.
This bulkhead area can usually be repaired by fabricating in a new section and cutting out all corroded metal.
With improved material and methods of sealing, priming, painting and treating metal than were available when new this now becomes a once only permanent repair.
Water ingress to the footwells can also occur through internal corrosion of the drains in the side of the sill panels. Once the drain tubes have rusted through they allow water to collect in the sill panel lower seam area to the floor pans, eventually rusting through to outer edges of the floor pans to sills.
The sill panels play a very important part in the structure of an SL and should not be patch repaired.
Fortunately this vehicles bulkhead was checked and confirmed in good condition, we did however replace both sill panels as part of this restoration.
Finally, finished in the striking colour of Blue Black Metallic the vehicle was wet flatted and machine polished to achieve the very best finish, then completely re-assembled, a great example of a facelift R107.
