Est. Repair Cost: £50–£200
Warning Signs:

Crank but no start, Intermittent stalling, Mystery electrical gremlins

What to Inspect:
  • Ask if the RCM has been "reflowed" or replaced
  • Check for consistent starting from cold and hot

Sticky Ignition Barrel

ModerateInterior & Trim

A internal pin in the ignition barrel can jam, preventing the key from turning to the "Start" position. This often requires a replacement barrel or a specialist "pin removal" repair.

Est. Repair Cost: £150–£400
Warning Signs:

Key won't turn, Key feels jammed or heavy

What to Inspect:
  • Test the ignition multiple times
  • Check if the key is original and not worn

Water Pump and Thermostat Failure

ModerateCooling System

The Mercedes-sourced water pump and thermostat housing can fail, leading to overheating. The thermostat housing is plastic and can crack, causing coolant loss.

Est. Repair Cost: £200–£500
Warning Signs:

Temperature gauge rising, Coolant smell from engine bay, Heater blowing cold, Coolant loss

What to Inspect:
  • Check the temperature gauge during the test drive
  • Inspect the thermostat housing for cracks
  • Look for coolant stains around the water pump

Roadster Soft-Top and Latch Issues

ModerateBodywork & Rust

The Roadster's fabric roof can develop leaks, and the latch mechanism can fail, preventing the roof from sealing properly. The roof hydraulics can also leak.

Est. Repair Cost: £200–£800
Warning Signs:

Water leaks into cabin, Roof not latching securely, Hydraulic noise from roof mechanism, Wind noise at speed

What to Inspect:
