Buying a Mercedes-Benz R-Class? Check its VIN history first

Reliability data covers the model. A VIN history report covers the exact Mercedes-Benz R-Class you're looking at — accident and write-off records, mileage rollback, outstanding finance and theft checks.

carVertical is our one disclosed affiliate partner — we earn a commission if you buy a report. It doesn't affect our reliability scores, which come from TÜV, ADAC, DVSA MOT and NHTSA data.

Reliability by Source

Each independent organization measures reliability differently. TÜV reports inspection defect rates by age band. ADAC reports pan-European breakdowns per 1,000 vehicles. NHTSA aggregates US consumer complaints. DVSA MOT data is the UK fleet's annual safety inspection — every car 3+ years old. Lower variance across sources = higher confidence in the composite.
