2016 Scania R450 12.7L Diesel · A6 CER

The Scania R450 typically achieves around 30–35 mpg (imperial) on diesel, meaning fuel costs will be a significant portion of the annual outlay – roughly £2,500–£3,000 based on current diesel prices and an average of 15,000 miles per year. Road tax for a vehicle of this class falls into the higher CO₂ bands, adding about £300–£400 per year. Insurance groups for 12‑litre diesel trucks are usually in the 30–35 range, translating to £800–£1,200 annually depending on driver profile. Maintenance on a vehicle with over 900,000 km can be costly, with typical yearly servicing, brake wear, and occasional major component replacement adding another £500–£800. Overall, expect an annual running cost in the region of £4,100–£5,400.

Inspect the engine for excessive smoke, unusual noises, and oil leaks – high mileage can lead to worn piston rings and turbo wear. Check the condition of the clutch and gearbox, as these components often require replacement after extensive use. Examine the brake system thoroughly, especially the brake discs and pads, given the vehicle's heavy‑load history.

Pay particular attention to the tyres and wheel bearings; the 2021 MOT advisory about missing tyre dates suggests that tyre records may be incomplete, so verify tread depth and look for uneven wear that could indicate alignment or suspension issues. Also, inspect the windscreen for the reported stone chip and ensure it has been properly repaired to maintain structural integrity.

Finally, review the service records for any major overhauls, such as timing chain or injector work. A lack of recent major service entries combined with the high mileage could signal impending costly repairs.
