Mercedes Benz Gl 320 (2008)
2008 Mercedes Benz Gl 320
CarHunch analysed 123 real MOT records for the 2008 Mercedes Benz Gl 320. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2008 Mercedes-Benz GL 320 passes its MOT on the first attempt 79.6% of the time, which matches the UK average almost exactly, but the real concern is that 44.7% of these vehicles have recorded a dangerous defect at some point—well above the typical threshold—suggesting structural or safety issues are genuinely common in this model. Buyers should factor in that nearly half of used examples will eventually develop a serious fault requiring urgent attention.
These vehicles average around 94,000 miles, which is reasonable for their age, yet they accumulate an average of 3.24 failures and 20.2 advisories per test cycle, indicating persistent wear and minor issues that pile up. Before purchase, get a pre-buy inspection specifically focused on the suspension, braking system, and undercarriage, since the high dangerous defect rate points to these areas as likely weak spots.
What to check before buying a 2008 Mercedes Benz Gl 320
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
