Buyer's guide
When shopping for a W129, verify complete service history and conduct a thorough inspection of the hydraulic hardtop system, which represents the model's most complex component. Early models command lower prices but later variants with V8 or V12 engines offer superior performance and tend to appreciate better over time.
Common issues
| Issue | Severity | Notes |
|---|---|---|
| Hardtop hydraulic pump seal failure | High | Expensive repair requiring system replacement, check operation before purchase |
| ABC suspension component wear | High | Costly suspension maintenance inherent to W129 design |
| Transmission seal leaks | Medium | Common in higher-mileage examples, factor in rebuild costs |
