2004 Isuzu Trooper 3.0L Diesel · CA04 ARX

The most recent MOT, carried out on 9 May 2025, was passed with no recorded defects, which on the surface suggests the vehicle now meets the legal safety standards. However, the preceding six years show a pattern of serious issues – extensive corrosion on both front and rear chassis members in 2022, fractured rear coil springs and a broken rear suspension in 2023, and a major rear chassis corrosion coupled with an excessively binding rear service brake in 2024. The 2025 pass therefore likely reflects remedial work rather than an inherent improvement in the vehicle’s condition; the overall maintenance trend has been deteriorating, with the latest result dependent on recent repairs that must be verified. At 131,916 miles over 22 years the average annual mileage works out to roughly 6 000 mi, which is well below the typical usage for a vehicle of this age. Such low utilisation often points to long periods of inactivity, a factor that can accelerate corrosion of body panels, under‑carriage and suspension components, and cause rubber and battery ageing even when the clock‑mileage is modest. The mileage itself does not explain the coil‑spring failures or brake binding, which are more indicative of age‑related metal fatigue and possible lack of regular service on the braking system. A prospective buyer should give the structural integrity of the chassis and body the highest priority. Inspect the off‑side rear and near‑side front and rear mounting points for deep rust, flaking paint or holes within the 30 cm zones identified by the MOT failures; any sign of compromised metal should be confirmed by a qualified panel beater. Examine the rear suspension for sagging, uneven ride height or any audible clunk when the wheels are rocked – broken coil springs often manifest as a soft, low‑frequency thump and can lead to uneven tyre wear. The service brake on the off‑side rear must move freely; a binding caliper will feel gritty or stiff under pedal pressure and may cause the vehicle to pull to one side or produce a shudder when braking. The steering box advisory for slight free play should be tested by turning the wheel at low speed; any looseness or wandering indicates worn rack or excessive play in the steering column that may need adjustment or replacement. Given the vehicle’s age and low mileage, a thorough age‑related check is essential. Verify that all four tyres have sufficient tread depth and that the sidewalls show no cracking, dry‑rot or bulging, which are common after years of storage. Test the 12‑volt battery voltage and, if possible, its cranking amperage, as batteries left idle for long periods lose capacity. Inspect all fluid reservoirs – engine oil, coolant, brake and power‑steering fluids – for colour, level and any signs of contamination; fluids should be replaced on a calendar basis even if mileage is low. Finally, confirm that the service book records regular oil changes, timing‑belt or chain maintenance (if applicable), and any rust‑proofing treatments, as these will give the best indication of whether the vehicle has been kept in a roadworthy state despite its intermittent use.
