Pre-purchase walkaround
1989 Mercedes-Benz 560SL (R107)
mileage unknown
Five-year cost to own, maintenance and fuel
~$25,500
The R107 560SL was the US-market top of the range roadster, overbuilt and heavy, sold only in North America. Ownership money goes into rust remediation, timing chain and top end service, and the mechanical fuel injection system, none of it cheap because parts are Mercedes and labor is specialist.

What to look for on this one
Every used example of this chassis has the same questions. The bands show when each tends to surface; the gold line is this car at 180,000 miles.
Timing chain and guide wear$900-$2,660 if not done
0typical window 80k-150k · this car: 180k, past it200k mi
M117 single row chains and their plastic guides age and wear, and a failure can bend valves on this interference engine. Rattle on cold start, chain slap, or a stretched chain reading past service limit.
Cooling system and radiator degradation$550-$1,600 if not done
0typical window 80k-150k · this car: 180k, past it200k mi
Original plastic tank radiators and aging hoses fail, and the heavy V8 runs hot when the system is tired. Overheating in traffic, seeping radiator end tanks, or a soft water pump.
Structural and cosmetic rustpriced only if found
Condition-driven, not mileage-driven, so it is not in the totals and inspection is the only answer. Bubbling paint at fenders, rockers, jacking points, floors, and around the battery tray.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Inspect rockers, front fender bottoms, jacking points, spare tire well, and battery tray for rust and prior filler.
02Cold start and listen for timing chain rattle before oil pressure builds.
03Check for oil at the front timing cover and valve cover gaskets.
04Test central locking and HVAC flap movement to gauge vacuum system health.
