The Essential Checklist Before Buying an Mercedes R129
Added on: November 2, 2022
Author: ak
The list of parts you need to check before you buy your SL.
I hope that this article helps you decide which car to buy and, if you want to restore an R129, how much it will cost. You will see why on the market you can find so many R129s and why there is such a price discrepancy.
First Look
Accident-free
Meter status
Engine: in this case it is better for a mechanic to check engine heating, water and oil temperature, oil pressure
Leaks
Gear box
Rust (wheel arches, sills under plugs)
Air condition
Cruise control
Condition of wooden elements
Door panels (scratches)
Varnish thickness (original paint 70–140, second paint around 200)
Brake discs
Tires (tread thickness, degree of wear on the inside and external side)
Soft top (actuators, roll bar, computer, pump, soft top condition)
Seat control
Coolant level
Central lock
Check the comparison of spare parts in the pre-facelift and face-lifted Mercedes R129.
