North American Models
Sales of the SL and SLC models begun in the US one year later than in Europe.
The R107/C107 since introduction on North American market sported quad headlights, and from 1974 front and rear bumpers had added 8 inches (203 mm) of rubber on each end to comply with the U.S. National Highway Traffic Safety Administration regulations.
When the first 350s were exported to the US, because of the strict horsepower robbing emission requirements, the US 350s were shipped with low compression 4.5 liter engines.
The 450 SL was produced until 1980. Model years 75 and 76 450 SLs suffered from vapor lock and hard restart because of the under-hood position of the catalytic converter. Starting in MY 77, the catalytic converter was moved to replace the resonator, located just behind the transmission in the exhaust system.
Next was the 380 SL imported from 1981 to 1985. The 380 SL was the least powerful of the US imported R107 roadsters. This engine came with a single row timing chain from 1981 through 1983. MYs 1984 and 1985 came with a double row timing chain from the factory. These early 380 models were plagued with chain failure problems and the problem was corrected by Mercedes-Benz, free of charge. Some models, however, escaped retrofit and may at some point fail as a result.
Another problem area for late 450 SLs and early 380 SLs was the automatic climate control system. Based on a "servo", which controlled coolant flow to the heater core, as well as vacuum to actuate the vents in the interior of the car, the system proved unreliable. It was installed on 450 SLs from 1978 through end of production in 1980, and continued on the 1981 MY of the 380 SL. Models produced prior to 1978 had a manual climate control system, models produced after 1981 received a more reliable automatic climate control system.
The more powerful 500 SL with 5.0 liter engine, produced from 1980–1989, was not available in the US through Mercedes-Benz and was popular in "gray market" import before the arrival of the 560 SL (only made for the USA, Japanese and Australian market) in 1986-1989.
Despite the larger 5.6 liter engine of the 560 SL, the 500 SL is recorded as being the fastest production 107 produced (mostly because of the lack of emission restraints) The 500 SL was published by Mercedes-Benz as having 0-60 mph times of 7.4 seconds for a top speed of 225 km/h (140 mph). Torque for the 500 SL is 296 lb·ft (401 N·m) at 3200 rpm and for the 560 SL 287 lb·ft (389 N·m) at 3500 rpm.

Famous quotes containing the words north, american and/or models:
“The recent attempt to secure a charter from the State of North Dakota for a lottery company, the pending effort to obtain from the State of Louisiana a renewal of the charter of the Louisiana State Lottery, and the establishment of one or more lottery companies at Mexican towns near our border, have served the good purpose of calling public attention to an evil of vast proportions.”
—Benjamin Harrison (1833–1901)
“Someone is always at my elbow reminding me that I am the grand-daughter of slaves. It fails to register depression with me. Slavery is sixty years in the past. The operation was successful and the patient is doing well, thank you. The terrible struggle that made me an American out of a potential slave said “On the line!” The Reconstruction said “Go!” I am off to a flying start and I must not halt in the stretch to look behind and weep.”
—Zora Neale Hurston (1891–1960)
“... your problem is your role models were models.”
—Jane Wagner (b. 1935)
