Should I Buy a Mercedes-Benz GLS 2020 in UAE? Complete Buyer Guide

Is the Mercedes-Benz GLS 2020 a Good Buy in UAE?

Its air suspension and reinforced cooling systems are well-adapted to GCC climates. However, with only 4 active listings at a median price of AED 173,700, buyers face limited selection and should prioritize thorough inspections.

What to Inspect Before Buying

Climate control test

Suspension diagnostic
- Cycle through all ride height settings 3 times; listen for compressor strain
Service records
- Demand proof of transmission fluid change (required every 60,000 km in UAE)
Undercarriage inspection
- Check for sand accumulation in wheel wells (indicates poor maintenance)
Turbo health check
- Accelerate hard from 80–120 km/h; watch for white smoke (turbo seal failure)

Verdict

Buy if:

You need 7-seat luxury with off-road capability (sand performance is excellent)
Can budget AED 20,000/year for maintenance and depreciation
Find a unit with verifiable service history

Avoid if:

You expect Japanese-brand reliability (repairs are 40% costlier than Lexus LX)
Primarily drive short distances (frequent cold starts harm the twin-turbo V8)
Need warranty coverage (most 2020 models are now out of factory warranty)

The GLS 2020 makes sense for UAE buyers who prioritize comfort over running costs, but only with proper documentation and a pre-purchase inspection at a Mercedes specialist.
