Choosing Your Perfect CLS Engine and Drivetrain

The heart of any Mercedes-Benz is its engine, and the CLS Class offers a palette ranging from smooth and efficient to ferociously powerful. Your choice will significantly impact the driving experience and ownership costs.

Engine Options Explained

Mercedes-Benz uses a naming convention that can be a bit cryptic. Here’s a breakdown of common CLS powertrains you might encounter:

• ‘350’ or ‘400’ (V6 or V6 Bi-Turbo): These models typically offered a good balance of performance and refinement for daily driving. They are smooth and capable for those who prioritize comfort over outright speed.

Tackling the Used CLS Market: What to Inspect

Buying a used CLS can offer exceptional value, but it requires diligence. Here’s a checklist to help you inspect a pre-owned model.

Mechanical Inspection Checklist

When test driving and inspecting a used CLS, pay close attention to these areas:

1. Engine: Listen for any unusual noises, such as knocking, ticking, or whining. Check for smooth idling when cold and warm. Inspect for any oil or coolant leaks under the hood or around the engine block.
2. Transmission: Shifting should be smooth and seamless, both in automatic and manual modes (if applicable). There should be no jerking, slipping, or hesitation. Test reverse and all gear selections.
3. Suspension: Drive over uneven surfaces and speed bumps. Listen for clunks, rattles, or creaks. The car should feel stable, not bouncy or wobbly.
4. Brakes: Engage the brakes firmly. They should be responsive and pull the car straight. Listen for grinding or squealing noises.
5. Tires: Check for even tread wear. Uneven wear can indicate alignment issues or suspension problems.
6. Exhaust: Look for excessive smoke (blue smoke might indicate oil burning; white smoke could be coolant). A healthy exhaust system should produce minimal visible exhaust in normal conditions.

Exterior and Interior Checks

Don’t overlook the visual and sensory aspects:

• Bodywork: Inspect for dents, scratches, or signs of rust, especially around wheel arches and sills. Check panel gaps for consistency – uneven gaps can suggest accident repair.
• Paintwork: Look for color variations or overspray, which are indicators of repaint work. A magnet can help identify areas that have been filled with body filler.
• Lights and Glass: Ensure all exterior lights are working correctly. Check the windshield and windows for chips or cracks.
• Interior Upholstery: Examine seats, carpets, and headliner for excessive wear, tears, stains, or sagging.
• Electronics: Test all electrical components: windows, locks, mirrors, sunroof, infotainment system, climate control, wipers, and all dashboard lights.
• Air Conditioning: Ensure it blows cold air effectively.

Maintenance History and Documentation

A comprehensive service history is crucial when buying a used Mercedes-Benz. Look for:

• Regular Servicing: Ideally, the car should have been serviced at recommended intervals, preferably by a Mercedes-Benz dealership or a reputable independent specialist.
• Recalls: Check if any manufacturer recalls have been addressed. You can often check this on the NHTSA website using the Vehicle Identification Number (VIN).
• Accident Reports: A vehicle history report (e.g., Carfax, AutoCheck) can reveal previous accidents or title issues.
