For sale is my Mini Cooper S R56 a seriously well-sorted example that's had extensive preventative maintenance and performance upgrades carried out to a very high standard. This isn't your average Cooper S; the car has been properly looked after with a huge amount of money and attention invested into both reliability and performance. The engine has undergone major work including a full timing chain kit and tensioner replacement, upgraded valve stem seals, rocker cover gasket replacement, and all major engine seals refreshed. The turbo oil feed and return pipes have also been replaced, along with a new high-pressure fuel system for peace of mind and strong performance. The engine has additionally been fully decarbonised, helping it run cleaner, smoother, and more responsively. Performance-wise, the car benefits from a Stage 1+ remap paired with an uprated intercooler, giving the car noticeably stronger pull and improved throttle response throughout the rev range while still remaining perfectly usable day to day. The braking setup has also been upgraded with a Brembo big brake kit and performance racing pads, offering excellent stopping power and confidence under spirited driving. Cosmetically, the car sits on freshly refurbished gloss black alloys and has been partially dechromed for a much cleaner, more aggressive look. A new coolant expansion tank has also recently been fitted. Overall, this is a genuinely enthusiast-owned Cooper S that's had the right work done combining reliability upgrades, tasteful modifications, and strong performance into one very well-maintained car. Drives exactly how a properly sorted R56 should.
