2011 BMW 3 Series 335i 4dr Sedan (3.0L 6cyl Turbo 6M)
The 335i sedan is not as good as claimed. The fact that the radio display is blanked out due to the incorrect polarization filter alignment is unforgivable. This is a safety issue, and BMW has known about it for years. The Infiniti G37 totally outclasses the BMW 335i.
Fix the radio display to start, put a 12V accessory outlet where it can be reached. Make a small indentation in the roof liner so that you can get your fingers under the visor, and more.
