The Mercedes-Benz R129 SL is a roadster which was produced by Mercedes-Benz from 1988 until 2001. The R129 replaced the R107 in 1989 and was in its turn replaced by the R230 SL-Class in 2002 for the 2003 model year.
The R129 was offered as a two-door roadster with an automated (electro-hydraulic), fabric convertible roof; colour-matched, automated tonneau cover; and a manually detachable hardtop that could be fitted over the stored fabric convertible roof and tonneau. It was available with a variety of powertrains across its twelve-year production, including a V12 option used in the SL600.
Designed in 1984, the R129 was based on the shortened floorpan of the Mercedes-Benz W124. The new SL-class was presented at the Geneva Motor Show in March 1989, with left-hand drive sales beginning that summer and right-hand drive sales in the autumn. It came runner-up behind the Citroen XM for the European Car of the Year accolade.[1]

Designed in 1984, the R129 was based on the shortened floorpan of the Mercedes-Benz W124[2] and featured many innovative details for the time, for instance electronically controlled damping (Adaptive Damping System ADS, optional) and a hidden, automatically extending roll-over bar. The R107's somewhat dated rear suspension with semi-trailing arms gave way to a modern multi-link axle. The number of standard features was high, with electric action for the windows, mirrors, seats and hydraulic convertible top.
This car has a distinction of being the first passenger vehicle to have seat belts integrated into the seats as opposed to anchoring to the floor, B-pillar, and transmission tunnel.
Starting in 1993 for the 1994 model year, R129 were re-designated. For example, 500 SL became SL 500. Starting in model year 1994, Mercedes-Benz offered special SL models from time to time, such as the Mille Miglia edition cars of model year 1994 or the SL edition of model year 2000.
1994 cars (for 1995 model year) had minor updates for the car
1995 onwards R129s for the 1996 model year featured a minor facelift for the car:
During 1996 for model year 1997, cars were the first year to have an option of the panoramic roof. Also newly available:
A second facelift occurred in 1998 for model year 1999 which featured:
Initially, there were three different engines available,
and joined in July 1992 by the
There was a choice of 5-speed manual or 4–5 speed automatic for the six-cylinder cars; the V8 and V12 could only be ordered with a 4-speed automatic gearbox.
In autumn 1993 Mercedes-Benz rearranged names and models. Also, the 300 SL and 300 SL-24 were respectively replaced by:
Only the 280 was available with a manual gearbox. SL 500 and 600 continued with their respective engines.
A second facelift, introduced in late 1998, comprised new external mirrors, 17" wheels and new bumpers. Also new were the engines,
The V12 engine remained unchanged.

The new Mercedes Benz R129 roadster was first introduced into the Australian market in May 1990 with the 500SL model.[3] [4] [5] [6] The 600SL followed in May 1993, while a 6 cylinder SL did not arrive until the SL280 in October 1995.
Only 38 cars of the 600SL/SL 600 were delivered to the Australian market.
Not all engines were offered in North America. The 1990 Mercedes-Benz SL base model was the 228 hp 300 SL version[7] (European 300 SL-24) equipped with a five-speed manual or five-speed automatic transmission, but it was the 322 hp 500 SL (with a 5.0-litre V8 engine) which made the most headlines. For model year 1993, the 600 SL was additionally introduced stateside.
The SL 320 replaced the 300 SL in the United States in 1994, but the SL 280 was not offered. The 6-cylinder SLs were dropped from the US lineup in 1998,[8] leaving just the V8 and V12.

AMG had already offered an SL version while still independent, the AMG 500 SL 6.0 of 1991. After being taken over by Daimler-Benz, there were several AMG SL-models available through D-B dealers.
The SL 60 AMG was the most numerous of these rare cars. Sold from 1993 to 1998, it used a 59561NaN1 V8 engine producing 3750NaN0 at 5,500 rpm.[9] AMG claimed a 0–1000NaN0 speed of 5.4 seconds. Its top speed was limited to 2500NaN0.
Extremely rare was the SL 72 AMG, with a 70551NaN1 engine, sold through Mercedes-AMG in 1995, and offering the most powerful V12 engine ever put into an SL up to that time with 5100NaN0. Only 35 cars were made.[10]
After a brief hiatus, the SL 73 AMG was offered with the new M120 engine 72911NaN1 from 1997 to 2001, with a bore x stroke of DOHC 4 valves per cylinder, fuel fed by naturally aspirated Bosch HFM fuel injection and a compression ratio of 10.5:1, producing 5180NaN0 at 5,500 rpm and at 4,000 rpm of torque,[11] which was later used also by Pagani in the Zonda, enabling the SL 73 to set off from 0 to in no longer than 4.5 seconds, while achieving a top speed of above-. Only 50 cars were made.[12] [13] [14]
Also very rare is the SL 70 AMG which was powered by a 70551NaN1 V12 engine developing 4960NaN0 at 5,500 rpm and a maximum torque of at 3,900 rpm. It was a bored out version of M120 6.0 V12 and with a longer stroke. Produced between 1996 and 1997 in 150 units.[15]
The SL 55 AMG was sold in the R129 body style from 1998 to 2001 in limited numbers (5.4L V8, 3490NaN0 at 5,500 rpm). It was the predecessor of the production R230 SL 55 AMG sold later, albeit was normally aspirated in the R129 and not supercharged as in its R230 successor. 65 cars were made.[16]
Only about 300 (without the SL 60) cars in the SL-class were customised by AMG prior to the 2003 model year.
In 1995 Mercedes released the Mille Miglia edition, to commemorate the 40th anniversary of Stirling Moss's win of the 1955 Mille Miglia road race. The limited edition was available in either SL 280, SL 320, or SL 500 guise; came in Brilliant Silver metallic; and had Evo II six-spoke polished alloys, red and black leather interior, carbon-fibre trim and extra equipment. Stirling Moss was given the first SL 500 built. According to the brochure of this special edition, only 600 pieces were to be built, however only 40 were built.
A special edition of 2002 SL 500/SL 600 was made to celebrate the 1930s Silver Arrow race car. It had full AMG body package, painted in Silver Arrow only special 777 metallic paint, special Silver Arrow designation on interior and exterior badging, two-tone silver and black interior, leather on steering wheel and seats, Silver Arrow illuminated sill plates, Silver Arrow leather bordered floor mats, special dark wood, and special BBS 2 piece wheels with polished stainless steel beauty rings. For the US market, only 1550 Silver Arrow units were produced; 100 units of the SL 600 and 1450 units of the SL 500. For the UK market, just 100 Silver Arrows were made, all of which were SL 500 models.
Several other editions were released of the 129 body SL. These include:
The R129 received heightened media attention in 1991 for two reasons.
Diana, Princess of Wales sold her Jaguar XJS to lease a metallic-red 500 SL and became the first member of the royal family to use a foreign car. This was not without controversy as it sparked a media storm as it questioned whether a member of the British royal family should drive a foreign car.[18] Media pressure eventually forced her to return the car to Mercedes-Benz in 1992. It now resides in the Mercedes-Benz Museum.[19]
Victor Chang, Companion of the Order of Australia and Australian of the Century (People's Choice Awards) was a pioneer of modern heart transplantation, fatally shot while driving his 500SL in Sydney.[20] [21]
