4 speed. Factory alloys. Same owner for nearly 30 years. Absolutely solid. Nice presentable driver. Finished in German Racing Silver and beautiful “Pagoda” design. The 2.3 litre six cylinder engine propels this W 113 chassis to very satisfying results. These pagoda cars have brought up to $200,000 in the last few years with 100’s sold for over $100,000. Same owner for decades from Eastern Washington well maintained, used sparingly, always garaged. 57,451 miles believed accurate.Production of the 230 SL commenced in June 1963 and ended on 5 January 1967. Its chassis was based on the W 111 sedan platform, with a reduced wheelbase by 30 cm (11.8 in), recirculating ball steering (with optional power steering), double wishbone front suspension and an independent single-joint, low-pivot swing rear-axle with transverse compensator spring. The dual-circuit brake system had front disc brakes and power-assisted rear drum brakes. The 230 SL was offered with a 4-speed manual transmission, or an optional, very responsive fluid coupled (no torque converter) 4-speed automatic transmission, which was popular for US models. From May 1966, the ZF S5-20 5-speed manual transmission was available as an additional option, which was particularly popular in Italy. Of the 19,831 230 SLs produced, less than a quarter were sold in the US.The 2,308 cc (2.3 L) M127.II inline-six engine with 150 PS (110 kW; 148 hp) and 196 N⋅m (145 lb⋅ft) torque was based on Mercedes-Benz’ venerable M180 inline-six with four main bearings and mechanical Bosch multi-port fuel injection. Mercedes-Benz made a number of modifications to boost its power, including increasing displacement from 2,197 cc (2.2 L), and using a completely new cylinder head with a higher compression ratio (9.3 vs. 8.7), enlarged valves and a modified camshaft. A fuel injection pump with six plungers instead of two was fitted, which allowed placing the nozzles in the cylinder head and “shooting” the fuel through the intake manifold and open valves directly into the combustion chambers. An optional oil-water heat exchanger was also available.Mercedes-Benz Chief Engineer Rudolf Uhlenhaut demonstrated the capabilities of the 230 SL on the tight three-quarter mile Annemasse Vétraz-Monthoux race track in 1963, where he put up a best lap time of 47.5 seconds vs. 47.3 seconds by Grand Prix driver Mike Parkes on his 3-liter V12 Ferrari 250 GT.
