Delving into the world of high-performance luxury cars often leads enthusiasts to the iconic Mercedes V12 Twin Turbo engine. These powerplants represent the pinnacle of automotive engineering, blending immense power with sophisticated technology. Recently, an exciting opportunity arose to explore a W221 series Mercedes, equipped with this legendary engine, offering a hands-on experience into the realities of owning such a machine.
Upon acquiring this majestic vehicle, a thorough review of its history became paramount. Despite boasting 83,000 miles on the odometer, the documented maintenance revealed a proactive approach to upkeep, offering both reassurance and a glimpse into potential ownership costs. Notably, a December 2019 service addressed cooling system components, including the radiator and condenser, along with a blower motor replacement. Prior to this, in October 2018, the ABS module was exchanged, preceded by the replacement of all four ABS sensors in July 2018 – hinting at a comprehensive resolution of an ABS issue. Further back, February 2018 saw attention paid to the hydraulic ABC (Active Body Control) system with a pump and corroded pipe being replaced. A significant service in December 2016 included an oil cooler, new batteries, and an EIS (Electronic Ignition Switch), showcasing the car’s complex electronic and mechanical systems.
Earlier maintenance records provided further insights. In January 2013, at 63,000 miles, spark plugs were changed, indicating long-term maintenance schedules adhered to. October 2012, at 61,000 miles, saw a gearbox control unit replacement and fluid/filter change, crucial for the longevity of the 5-speed transmission, which, interestingly, was retained in W221 V12 models throughout their production run, potentially avoiding early 7G Tronic transmission issues. Adding to the vehicle’s features, September 2012 saw the installation of an iPod kit, backup camera, DAB module, and multicontour seat module, highlighting upgrades focused on technology and comfort.
While regular services were expected, the documented replacements of gearbox fluid, spark plugs, and ABC fluid provided peace of mind. The seller mentioned a coil pack replacement, although undocumented, suggesting ongoing minor maintenance. Removing the engine covers revealed the impressive Mercedes V12 twin turbo engine in all its glory, a moment of both excitement and a slight sense of the engineering complexity within.
Initial driving impressions, including navigating through Bristol traffic, underscored the car’s dual nature – powerful yet refined. A surprising discovery was the car’s integrated fridge, larger than anticipated and capable of holding four wine bottles, alongside a rear table, adding a touch of luxury. The fridge functionality was confirmed, though wiring irregularities suggest past modifications requiring further investigation to ensure proper operation.
A minor issue noted was an inoperative remote boot closing. Fuse checks proved negative, suggesting a potential need for Star diagnostics to pinpoint the cause, possibly a software or ECU-related issue. This initial exploration into Mercedes V12 twin turbo ownership reveals a fascinating blend of robust performance, documented maintenance, and minor quirks to address, setting the stage for an engaging ownership experience.
