Should I check the MOT history before buying a 2017 Mercedes Benz G Class?

The 2017 G-Class impresses on first MOT with a 89.6% pass rate, nearly 10 points ahead of the UK average—a genuinely strong result for a premium SUV of this age. Dangerous defects are uncommon, affecting only 11.1% of vehicles, so structural and safety concerns aren't a red flag for this cohort.

These cars are running light at under 34,000 miles on average, which explains the healthy pass rate and relatively modest failure rate of 0.76 per vehicle. The 4.4 advisories per test suggest routine wear items like suspension and brakes need attention, but nothing dramatic—have a pre-purchase inspection focus on those areas and you'll know exactly what you're buying into.
