Buyer's guide
Purchase examples with full service history and low-mileage CLS63 AMG variants for the strongest long-term value and performance credibility. Inspect suspension components and transmission fluid carefully as these systems represent the most significant maintenance costs on out-of-warranty examples.
Common issues

|---|---|---|
| 7G-Tronic transmission shudder at low speeds | Medium | Common after 80,000 miles, fluid service often resolves |
| Air suspension compressor failure | High | Expensive repair costing $2,000-$4,000 |
| Direct injection carbon buildup | Medium | Affects higher-mileage examples, requires professional cleaning |
