A facelift that defined an era

The mid-1990s were a golden era for the Mercedes SL, and 1996 was a particularly pivotal year. Just in time for the U.S. 1996 model year, the R129 SL received its first major facelift. While at first glance the changes seemed subtle, they marked an important technological and design evolution that kept the SL at the top of the luxury roadster segment.

A tailored update for the American market

The U.S.-spec models inherited most of the revisions made to the European versions, with a few market-specific tweaks to comply with federal regulations. For example, the front indicator lens units remained unchanged to meet U.S. standards.

The pricing structure for the American lineup carried over from the previous year with only minor adjustments:

• SL320 – approx. €72,800
• SL500 – approx. €83,600
• SL600 – increased slightly to around €113,460, but now with ESP fitted as standard.

All models featured a five-speed automatic transmission, but only the V8 and V12 models initially benefited from the new 5AT gearbox.

Suspension, lighting, and comfort upgrades

The SL600 received Mercedes’ latest adaptive damping system (ADS) as standard, now featuring manual ride height adjustment for the first time on the U.S. market. Buyers of the SL320 and SL500 could opt for ADS for an additional €3,960.

Another highlight was the introduction of gas-discharge xenon headlights, also standard on the SL600. However, due to regulatory constraints, they couldn’t be combined with the headlamp wash/wipe system. For the SL320 and SL500, xenon lighting was available as a €880 option.

Comfort-oriented features expanded as well:

• Heated seats: €550

• Multi-contour seats: €350 per seat

• ASR traction control for SL320: €1,120

• ESP upgrade for SL500: €1,740

Following the example of the S600, the 1996 SL600 for the U.S. also received two-tone Exclusive leather upholstery. The refined interior design — paired with ESP and the adaptive chassis — justified the modest price increase compared to the previous model year.

Technology that looked ahead

Mercedes-Benz also brought new onboard diagnostics (OBD-II) to all U.S. SL models for 1996, a step ahead of European regulations that wouldn’t mandate the system until 2001. This upgrade allowed more accurate troubleshooting, better emissions control, and more precise vehicle testing.

Meanwhile, small but thoughtful details improved the overall user experience: grey secondary km/h speedometer markings replaced the previous orange ones (improving visibility of mph markings), cupholders became standard (a must-have in the U.S.), and floor mats were finally included in the package instead of being a €93 accessory.

Performance and market response

In an all-out performance test, Road & Track compared the SL600 against the Porsche 911 Turbo and Dodge Viper GTS. While the SL wasn’t the fastest, its silky V12, imperceptible gearshifts, and effortless character stood out. Impressively, it even beat the Chevrolet Corvette LT4 in the 0–100–0 km/h test.

Mercedes-Benz passenger car sales in the U.S. grew significantly from 76,752 units in 1995 to 90,844 in 1996. The SL line remained steady, with a slight drop of just 108 units — still accounting for 7.6% of Mercedes’ U.S. market share. Among them, around 680 units were SL600s and roughly 3,500 were SL500s.

Global pricing snapshot

In the UK, prices for the facelifted models rose slightly:

• SL280 – approx. €66,580

• SL320 – approx. €72,890

• SL500 – approx. €93,950

• AMG model – €107,040

• SL600 – €118,950

In Japan, the SL320 debuted at around €58,800, making it a more affordable alternative to the SL500. Even Australia expanded its lineup with the SL280 at €185,700, alongside the SL500 at €265,000 and SL600 at €340,500.

Conclusion

The 1996 facelift didn’t radically change the R129 SL’s looks — it didn’t have to. What Mercedes-Benz achieved was a carefully measured upgrade: refined technology, enhanced safety, and subtle design details that reinforced the car’s status as the world’s benchmark for luxury roadsters.

Nearly three decades later, these facelifted R129 models remain some of the most desirable classic Mercedes convertibles, combining timeless design with cutting-edge (for the time) engineering.
