1985 Rolls Royce 6.8L Petrol · 5 MJO

Fuel costs for a 6,750cc petrol V8 of this era are substantial — expect high-teens mpg at best, dropping to low double figures in urban driving. Assuming modest annual mileage of around 1,500 miles (typical for a collector car), fuel alone could easily cost £600-£900 per year at current prices. If the vehicle is registered as historic (over 40 years old and unmodified), it will be exempt from road tax, which is a significant saving. Otherwise, expect a substantial annual VED bill given the engine size.

Insurance for a 1985 Rolls-Royce will reflect its value and specialist repair costs. Even with agreed-value cover, premiums of £400-£800 per year are typical, and you will likely need to seek out a specialist classic car insurer rather than a mainstream provider. Maintenance is where the real expense lies: a routine service at a marque specialist can easily exceed £1,000, and any electrical, hydraulic, or suspension work can run into four figures. Budget conservatively and assume at least £2,000-£4,000 per year in maintenance and repairs for a car of this age, even if it appears to be in good condition at the point of sale.

Overall estimated annual running cost (excluding major repairs): £1,500-£2,500. With realistic allowance for occasional specialist work, this could easily double.

The single MOT pass in June 2022 noted no defects, which is positive, but it tells you nothing about the period since. Start with a physical inspection of the bodywork for corrosion — older Rolls-Royces are known for rust in the sills, wheel arches, boot floor, and around the screen seals. Pay close attention to the panel gaps and shut lines, as poor alignment may indicate accident damage or substandard repair work. Inspect the chassis and underside on a ramp, looking for evidence of welding, patch repairs, or underseal hiding corrosion. The 6,750cc V8 engine should start cleanly from cold without excessive smoke; blue smoke on start-up suggests valve guide wear.

Check the cooling system thoroughly — old rubber hoses, the radiator, water pump, and thermostat should all be inspected for leaks and signs of recent replacement. Test all electrical systems methodically, as wiring loom degradation is common in vehicles of this age. Examine the suspension for play in the bushes, shock absorbers, and self-levelling components if fitted. Brakes should feel firm, with no pulling to either side; check for hydraulic fluid leaks and the condition of the discs and pads, which are expensive to replace. Tyre age (look for the DOT date code) and condition are also a useful indicator of how the car has been stored.

Finally, verify the operation of every accessory: climate control, electric windows, seats, mirrors, and the trademark Rolls-Royce equipment. On these vehicles, many electrical issues stem from deteriorated switchgear and perished rubber seals. A pre-purchase inspection by a recognised Rolls-Royce or Bentley specialist (not a general garage) is not optional — it is essential, and should cost around £300-£500. Any seller who objects to this is best avoided.
