1994 Nissan Patrol 4.2L Diesel · 7 REG

Fuel economy from the 4.2-litre diesel Patrol is poor by modern standards, typically returning around 18-22 mpg, which at current diesel prices could mean £3,500-£4,500 per year in fuel alone depending on mileage. Road tax for a vehicle of this age is generally the standard pre-2001 rate, but you should confirm the current VED band directly with DVLA. Insurance is likely to be reasonable in itself, but finding a specialist insurer willing to cover a 32-year-old off-road diesel is important to confirm before purchase.

Maintenance costs are the major concern. Parts for older Japanese imports are increasingly hard to source in the UK, and specialist labour rates will apply. Budget at least £1,200-£2,000 per year for routine maintenance, and set aside a further contingency for major items such as injector replacement, turbo servicing, or chassis repair. Overall estimated annual running cost is approximately £3,000-£4,500 once fuel, tax, insurance, and maintenance are accounted for.

Start with the two items already flagged by MOT testers: the rear brake discs, which were noted as worn and pitted in June 2026, and the nearside front anti-roll bar linkage ball joint, which had slight play in April 2024. Both of these may have deteriorated further since the advisories were issued and should be inspected and likely replaced. Given the mileage, also pay close attention to the condition of all suspension bushes, shock absorbers, springs, and steering components, as these wear items accumulate over time on a heavy off-road vehicle.

Beyond the MOT-recorded items, inspect the chassis thoroughly for corrosion, particularly around the suspension mounting points, the rear crossmember, and the outriggers. Check the engine for oil leaks from the sump, rocker cover, and rear main seal, and listen for any unusual knocking or timing chain noise on start-up. Examine the cooling system for leaks and condition of hoses and radiator, as overheating can cause head gasket failure on older diesels. Finally, test the four-wheel-drive system, transfer box, and diff locks to confirm they engage smoothly, and check for excessive play in the propshaft universal joints.
