MERCEDES-BENZ The SLK R170

MERCEDES-BENZ SLK R170 Revised 2026 Edition Complete Model History, Engineering, Special Editions and a Detailed 30-Page Buyer’s Guide A well-maintained SLK R170 can be an enjoyable, practical and increasingly collectible modern classic. A neglected example, however, may conceal corrosion, electrical faults, roof problems and deferred maintenance that can lead to substantial repair costs. This revised edition combines the complete history and technical development of the first-generation SLK with a detailed 30-page buyer’s guide. Introduced in 1996, the R170 brought the compact roadster into a new era. Its electrohydraulically operated Vario-Roof combined open-air driving with the security and practicality of a fixed-roof coupé. The model range developed from the original SLK200 and SLK230 Kompressor to the later SLK200 Kompressor, SLK320 and high-performance SLK32 AMG. The major model update of 2000 brought numerous technical and stylistic improvements. This revised 2026 edition is a large-format, full-color reference covering model development, engines, transmissions, Vario-Roof technology, special editions, tuner conversions, production information, originality and the areas that should be examined before purchase. The book covers: • COMPLETE MODEL HISTORY From the SLK200 and SLK230 Kompressor to the SLK200 Kompressor, SLK320 and SLK32 AMG, including the important 2000 model update and the differences between early and later cars. • ENGINES AND ENGINEERING M111 four-cylinder and M112 V6 engines, supercharger systems, manual and automatic transmissions, suspension, steering, braking systems and the principal technical developments introduced during production. • VARIO-ROOF, ELECTRONICS AND K40 RELAY The electrohydraulic roof mechanism, pumps, cylinders, switches and seals, together with common electrical concerns, the K40 relay module and other systems that can affect reliability. • SPECIAL EDITIONS AND TUNERS The Final Edition and other special versions, together with interpretations by Brabus, Carlsson, RENNtech and additional specialists. • REFERENCE AND ORIGINALITY INFORMATION VIN decoding, data cards, production figures, factory equipment, paint colors and upholstery combinations help owners identify individual cars and understand their original specification. • DETAILED 30-PAGE BUYER’S GUIDE Bodywork, corrosion and previous repairs, engines, oil leaks, transmissions, suspension, brakes, electronics, roof hydraulics, water ingress, interior condition, service history and other areas where age or neglected maintenance can become costly. Unlike a conventional buyer’s guide, this book also presents the complete history and technical development of the R170. Unlike a general model history, it provides practical guidance for inspecting, purchasing and owning these distinctive compact roadsters. Whether you are considering purchasing an R170, already own one, or simply appreciate the first-generation SLK, this carefully researched and richly illustrated book offers a comprehensive guide to its history, engineering and many variations.
