Peak-era Mercedes build quality.
Mercedes-Benz SL-Class R129
Why it qualifies
Peak-era Mercedes build quality. M119 V8 (SL500) and M120 V12 (SL600) are bulletproof. SL73 AMG (6-figure car, ~85 built worldwide) is a unicorn.
Watch out for
- V12 SL600 maintenance cost (40+ spark plugs)
- ABC hydraulic suspension repair (~$5k)
- Convertible top hydraulics
- Harness chafing on older cars
