2016 BMW Z4 sDrive28i M Sport Convertible 43,739 miles, FSH A genuinely well-specified, low-mileage example of the final-year E89 Z4. Finished in blue with cream leather one of the most flattering and increasingly sought-after combinations on this generation. The 2.0-litre TwinPower Turbo (245 bhp, 0-62 in 5.7s) is paired with BMW's signature folding electrohardtop coup refinement at the touch of a button, full convertible in around 20 seconds. M Sport specification brings the aggressive bodykit, alloys, sports suspension, M steering wheel and sports seats. 1,500 audio upgrade (parts only). The factory system has been significantly uprated, with the only visible element being a pair of bass speakers neatly mounted behind the seats see photos. They sit in the natural dead space behind the cabin without intruding on seat travel or boot capacity, and were installed to a high standard. Everything else is hidden; the factory head unit and trim are retained throughout. The result is a system that genuinely works with the top down at motorway speeds the single biggest weakness of the standard Z4 audio. Receipts available. Fully reversible if the next owner prefers stock. Drives exactly as a rear-wheel-drive BMW roadster should composed, quick, and far more usable day-to-day than a Boxster or SLK thanks to the folding hard top. At 43k miles with full service history, this car has averaged well under 5,000 miles a year and presents accordingly. A proper modern classic in waiting, and one of the last truly analogue BMW sports cars before the G29/Supra-platform era. Viewing and inspection welcomed happy to accommodate an independent pre-purchase inspection.
