          Introduction
          
          
          The R107 body shape was first introduced to Europe in 
          1970 as the 350SL, with the car being made available to 
          Australia and the USA the following year.
          
          In 1979 Mercedes released the 450SL Roadster, originally
          released as a 350SL (4.5), with the name being "officially" 
          changed to 450SL one year later.
          
          The main reason for the release of the 450SL was to enable 
          Mercedes engineers to cope with more stringent US anti 
pollution legislation. In fact, the increase in engine 
          size was necessitated out of the engines loss of power 
          after the anti-pollution gear was attached.
          
          Without wishing to be political, one really does wonder 
          the reasoning of legislators that forced so many car manufacturers 
          of the time to increase engine size and therefore fuel 
          consumption in a bid to cut down on pollution.
          
          That said, many believe the 450SL to be the pick of the 
          R107 range (which includes the 350, 380, 560 and 280SL's). 
          Why?, because of the longevity and simplicity of the cast 
          iron block V8 engine, with matched bullet proof 3 speed 
auto transmission.
          
          The engine featured an advanced single overhead camshaft 
          design and was a torque monster, loafing happily along 
          at any speed, from its 550rpm idle up to its 6,000rpm 
          redline. 
          
          Various changes to the engine systems, particularly in 
          the US, saw power further decline to just 160bhp, although 
          such changes occurred during 1980, the last year of the 
          450SL. The majority of R107 SL's on the road today have either 
          been restored or are waiting to be restored, being around 
          25 years old.
          
          The value of such cars can vary wildly - 
          but the good news as this model is fast becoming a collectors 
          classic with values appreciating. Parts for the 107 are readily sourced from Germany and 
          the US, and the 450SL today represents a fantastic car 
          to own and drive in today's traffic.
