Testing the waters. For sale is my BMW M135i (F40) 306bhp. I've owned this car for a few months, and enjoyed driving it but looking to upgrade to M340d/i so may sell this car for the right price. It's a perfect blend of comfort and performance. The car has rare spec which is hard to find (listed below). The car has full service history (last service was August 2026), and all services have been carried out by BMW. It has new Michelin Pilot Sport 5 tyres x4 (installed in August 2026 Costing £400), recent 4 wheel alignment, and new brake pads and discs all round (costing over £1000). The car is HPI clear and has no previous accident history. Low mileage at 18,500 miles which makes it the lowest mileage, high spec M135i on the market. The car is in perfect condition as suggested by the BMW health report shown in pictures (and video available upon request with video walkaround of the underside of the car to show suspension components, brakes, and tyres). Another benefit of this car is that it is the 2019 version which means that the ECU and Gearbox are unlocked. This allows massive tuning potential for those interested in gaining more power and torque. Tuning this car can potentially take it close to 400bhp safely. Vehicles of this model that are 2020 or newer are very difficult and expensive to tune due to locked ECU's. However, currently this car is fully stock with no tunes or remaps. The car has many features such as: - Panoramic Sunroof (another option that isn't easy to find) - Heads up display - Reverse Camera - Leather Electric Memory Seats - Adaptive M Suspension (extremely rare, making the car really comfortable to drive). Without this, the car feels really uncomfortable. There are very few M135i models on auto trader with this spec. So far, this is the only one on the market with this mileage at this price. - BodyKit included separately. - Comfort Access which means keyless entry and lock and electric boot lid. - Heated steering wheel - and much more It is very difficult to find a clean example with high spec like this. I am not in a rush to sell, just interested to see what interest I receive in the car at this price point. For the right price, I'd be willing to sell otherwise I will keep the car. Please call me for more information. Please note: Test drives are only possible with proof of comprehensive insurance for this vehicle.
