The Mercedes-Benz C107 SLC was the fixed-roof coupe version of the iconic R107 SL roadster, produced from 1971 to 1981. To create a true 4-seat coupe, engineers stretched the SL's wheelbase by 14 inches, adding a functional rear seat and distinctive louvered panels behind the rear side windows. Engine options ranged from a 2.8-liter inline-6 in the 280 SLC to V8s in the 350, 450, and later 380 and 500 SLC models.
Collectors are drawn to the SLC's unique combination of classic R107 styling and grand touring practicality. While less common than its convertible sibling, it offers a more rigid structure and a quieter ride. The most desirable models are the rare, lightweight 450 SLC 5.0 and 500 SLC, which were homologation specials for rallying and featured aluminum hoods and trunk lids.
The market for the C107 SLC remains very accessible, with average prices hovering around $14,000. This makes it an excellent value compared to the R107 SL convertible. While standard 450 SLCs are plentiful, the limited-production 5.0 and 500 SLC models are true collector items and trade for significantly higher prices, often exceeding the top end of the typical market range.
Buying Tips
- Check for rust thoroughly, especially in the front fenders, rocker panels, floor pans, and around the trunk seal.
- The automatic climate control systems are complex and notoriously expensive to repair. Verify that both the heat and A/C function correctly through all vents.
- Early M117 4.5L V8s used a single-row timing chain that can fail. Check records for an upgrade to the more durable dual-row chain setup.
- Inspect the front and rear subframe mounts for cracks and deterioration, as replacement is a labor-intensive job.
- Sun damage is common; look for cracked dashboards, faded wood trim, and brittle leather or MB-Tex, as interior restoration is costly.
Prices for the C107 SLC range from under $1,000 for project cars to nearly $50,000 for exceptional examples.
