2005 Isuzu 3.0L Diesel · MJ 5173

The 3.0-litre Isuzu diesel is a relatively large engine for a vehicle of this size, so fuel economy is likely to be in the 28-34 mpg range depending on use, which is modest by modern standards. Road tax for a diesel of this age and 3.0-litre capacity will fall into the higher pre-2017 bands, likely £290-£305 per year, though vehicles over 40 years old become exempt, which is still some years away. Insurance group is not stated in the available data, but buyers should obtain quotes as parts availability for older Isuzus can be more limited and therefore pricier. Annual maintenance is likely to run £500-£900 given the age and the failure items observed, with brake and suspension work likely to dominate any near-term spending. Estimated annual running cost: £1,400-£1,800 including fuel, tax, insurance and routine maintenance.

Start with a thorough underbody inspection on a ramp, as the MOT data flags brake pipe corrosion on both nearside and offside front pipes, the rear brake pipe, and the pipes were greased in 2025 as a temporary measure which suggests an MOT advisory rather than a permanent fix. Inspect the front upper suspension arms and ball joints, particularly nearside, which progressed from a slight play advisory in 2024 to a failure in 2025, and check the offside for similar wear. Have the ABS system scanned for fault codes since the 2025 test recorded an illuminated ABS warning lamp, and clarify whether the underlying issue has been rectified since. Examine all four tyres for cuts, uneven wear and age-related cracking, as the 2026 test noted a cut in the offside front inner tyre. Finally, check for oil leaks from the 3.0-litre diesel engine, condition of the timing belt (if due for replacement this is a £400-£600 job), and look for corrosion around the wheel arches, sills and subframe, which are common MOT failure points on vehicles of this vintage.
