Cabin Materials And Layout
Inside, the 135i features quality soft-touch plastics, available leather surfaces, and sporty front seats with good lateral support. The center console layout groups climate, audio, and iDrive controls intuitively, though precise button placement requires a short learning curve for new users.
Space And Practicality
Despite its compact coupe profile, the 135i offers generous headroom and well-contoured rear seating. The trunk provides ample cargo capacity, and rear seats fold down to expand storage, making the car suitable for both personal use and light hauling needs.
Refinement Features

Ownership Considerations
Maintenance, Reliability, And Costs
Scheduled maintenance follows BMW intervals, with service including synthetic oil changes, brake fluid, and cabin filtration. Typical repairs involve aging bushings, rear shocks, and occasional turbocharger or valve cover gasket issues, so budgeting for wear items is wise for high-mileage ownership.
Final Recommendation
- Verify service history and receipts for maintenance and repairs
- Inspect suspension components, bushings, and rear shocks for wear
- Check turbo, valves, and coolant system for early leak or pressure signs
- Test drive for steering feel, clutch response, and interior electronics
