Owners rave about the exhilarating driving experience, citing the responsive handling and powerful acceleration as standout features. With 300 horsepower and 300 lb-ft of torque, this car can go from 0 to 60 mph in just over five seconds. The rear-wheel-drive layout and well-tuned suspension make it a joy to navigate through twisty roads. However, some owners have noted that the ride can be a bit harsh, especially on rough surfaces, which is something to consider if comfort is a priority.
Common Problems
While the 135i has its merits, it’s not without its issues. Owners on various forums have shared their experiences with common problems that can arise over time. Here are some of the most frequently reported issues:
