1995 Chevrolet GMC GMC 5.7L Petrol · M346 ABV

The vehicle is currently roadworthy, but the maintenance history reveals a worsening trend regarding structural integrity and fluid lines. While the vehicle passed the March 2026 test at 187,362 miles, this followed a significant failure just five weeks prior. The February 2026 failure highlighted high exhaust carbon monoxide and lambda readings, alongside persistent issues with corroded brake pipes. The fact that the vehicle required multiple repairs to clear faults and pass suggests a reactive maintenance approach rather than preventative care. At 31 years old, the mileage of 187,362 miles represents a consistent usage pattern of approximately 6,000 miles per year. However, there is a notable four-year gap between the February 2020 and 2021 tests, followed by a rapid accumulation of nearly 6,000 miles in a short window. This pattern suggests the vehicle may have sat stationary for long periods, which often correlates with the accelerated degradation of rubber components and the onset of surface corrosion as seen in the record. A prospective buyer must conduct a thorough physical inspection of the chassis and frame, as structural corrosion has appeared on all four corners of the vehicle since 2021. The tester specifically noted corrosion on the nearside and offside front structures, as well as the rear sections, in previous tests. Furthermore, the recurring presence of grease on the brake pipes is a common tactic used to hide leaks or advanced corrosion, necessitating a close check of the integrity of the metal lines. The buyer should also inspect the front suspension thoroughly. The record shows a history of deteriorated ball joint dust covers and worn upper arm bushes. Given the recent failure related to emissions, the engine's fuel system and exhaust manifold should be monitored to ensure the high carbon monoxide levels and lean-of-mixture issues identified in the February 2026 test have been properly addressed beyond just a temporary fix.
