Strengths
- AMG-developed chassis is genuinely sporty
- M177 V8 sounds tremendous
- Rear-axle steering on V8 trims
Weaknesses
- Pricing has crept above $200k on SL 63 S E
- Soft-top divides hardcore SL fans
- Cabin space tighter than R231
Notable tech
- MSA platform (AMG-developed)
- 9-speed AMG SPEEDSHIFT MCT
- RWD (SL 43) or 4MATIC+ AWD with rear-axle steering
- Soft-top (replaces R231 folding hardtop)
- AMG-only branding (no non-AMG SL)
Common issues
- Some early MBUX freezes
- Soft-top motor wear
- M177 valve seal failures (long-term)
Used-market budget
$110,000
Typical price point for a well-maintained example with full service history. Cars priced significantly below this often require remedial work.
