BMW 135i - Enthusiast Owned - Extensively Maintained - Tastefully Upgraded Reluctantly offering my BMW 135i for sale. This has been a fantastic car to own and has been maintained proactively rather than reactively. It's an honest, well-sorted example that benefits from a substantial amount of recent maintenance alongside sensible performance upgrades. The car drives superbly with the effortless performance you'd expect from the turbocharged straight-six, while remaining perfectly usable as a daily driver. Everything works as it should, and the car has been looked after regardless of cost. Recent maintenance includes: - Genuine BMW valve cover and valve cover gasket. - Genuine BMW oil filter housing gasket. - New water pump. - New battery (last year). - New ignition coils and spark plugs (last year). - Aluminium "Mickey Mouse" coolant flange upgrade. - RB external PCV valve upgrade. - Oil catch can fitted. - New upstream O2 sensors (last month). - MTEC front brake discs. Performance & supporting modifications: - JB4 tuning system fitted. - 7" stepped front mount intercooler. - Aluminium charge pipe upgrade. The car has never run a more aggressive setup, although a pair of decat downpipes will be included with the sale should the next owner wish to fit them. Included with the sale: - Spare wastegate actuators. - Genuine BMW 1M oil cooler ducts (new). - Genuine BMW 1M front number plate mount. - Decat downpipes (not fitted). For complete transparency, the car has a slight wastegate rattle on the overrun/off throttle, which is common on these engines and does not affect how the car drives. Spare actuators are included with the sale should the next owner wish to address it. Overall, this is a well-maintained, enthusiast-owned 135i that's had the expensive and common maintenance items taken care of, along with sensible upgrades to improve reliability and performance. It's ready to be enjoyed by its next owner. Happy to answer any questions, provide additional photos or discuss the car in more detail. Viewings and inspections are welcome.
