2009 Mercedes-Benz S-Class W221 350 Blue Efficiency 3.5 petrol from Cyprus

Summary:

Expensive but worth it

Faults:

All the car's faults are minor; I call them minor faults because they are not mechanical problems.

Keyless entry system handles can fail due to wiring damage, a problem that can be easily repaired.

Power windows can stick due to a damaged regulator mechanism or a fault in the control module that operates them. This has happened to me repeatedly; it's tiring, but not serious.

The air conditioning failed due to a dirty fan or blockages in the engine compartment drains, which can affect the operation of the electronics if not addressed immediately.

There are people who have this same car and have trouble starting it; fortunately, it never happened to me.

General Comments:

The best thing about the car, like any good Mercedes, is its comfort, luxury, and convenience. The Airmatic air suspension, which scans the road, provides a very smooth ride and can lift the body to absorb bumps, making road trips exceptionally comfortable.

The car stands out for its poise on highways, allowing high speeds with the engine at low revs, which contributes to a relaxed experience.

It incorporates systems such as a 360-degree camera and automatic parking assistant, which make maneuvering easier.

The 3.5-liter petrol engine consumes quite a bit of fuel, but with the necessary maintenance it is more than reliable and durable. Regular and timely engine maintenance is crucial to avoid problems with the injectors and turbocharger, which are vulnerable points.

Maintenance and spare parts costs are quite expensive, commensurate with a premium brand, but if you're being responsible, it's a car that requires few servicings, only basic ones. It may not be a W115 or W123, but with so much modern technology, you can say it's quite reliable.

Would you buy another car from this manufacturer? Yes
