The Mercedes-Benz SL (R107) of the early 1980s embodies classic style and open-top motoring. Popular among enthusiasts in New Zealand, its blend of luxury and performance is undeniably appealing. However, owning a vehicle of this age requires proactive maintenance and awareness of potential issues.
Common issues include rust (especially around wheel arches, sills, and floor pans), fuel injection problems, worn suspension components (ball joints, bushes), leaking hydraulic systems (soft top mechanism), failing air conditioning systems, and deterioration of interior trim and seals.
WOF failures are commonly related to rust (structural or safety related), worn suspension components (excessive play in ball joints or bushes), faulty lights, brake condition (corrosion, leaks), and exhaust leaks. Ensure the soft top mechanism is functioning correctly, as this is often overlooked but can be a WOF issue if it presents a safety hazard.
The R107 SL offers a refined driving experience. Engine options typically include inline-six and V8 configurations, offering varying levels of performance. The build quality is generally robust, but time takes its toll. Look out for rust, especially in areas prone to moisture. Suspension components can wear, affecting handling. Early fuel injection systems can be temperamental, requiring specialist attention. Regular servicing is key to keeping these classics on the road.
