2023 BMW Z4 20i M Sport in Thundernight metallic. One owner from new, 16,930 miles averaging just 4,900 miles a year. Full BMW main dealer service history with stamped records for 2023, 2025 and most recently October 2026 at 16,978 miles. The original owner spent £1,135 on factory options. M Sport Pro Package, Metallic Thundernight at £695 (marked Very Rare by AutoTrader, a striking purple that stands out in a sea of silver and black roadsters), Harman Kardon loudspeaker system at £440 which transforms the cabin acoustics, M Sport brakes with blue calipers for stronger stopping power, Vernasca leather in black with decorative stitching, and WiFi hotspot. Recent brake fluid change and fresh rear tyres fitted at the October 2026 service, so you're not inheriting deferred costs. Brake fluid absorbs moisture over time and loses effectiveness, replacing it on schedule is a sign of thorough maintenance. The fabric soft-top opens or closes in 10 seconds at speeds up to 31 mph, no need to stop or get out. Rear-wheel drive with 50:50 weight distribution means the Z4 steers with precision and feels alive in corners. The eight-speed ZF automatic is quick to respond when you use the paddles, smooth when left in auto. MOT to March 2027. Supplied with 2 keys, fitted mats and 6 months complimentary warranty.
