Our CT is not F-Sport (no black trim and no F-Sport grill) but has Mark Levinson audio, LED with washer, leather seats automatic adjusting for 3 persons, sunroof, 13MM navigation, funny mouse comand to screen, rain sensor for windshield wipers, funny sounds when getting close to someting with both front and rear of car and 17" wheels, automatic dimming rear view mirror. Have probably forgotten something and maybe not know what else is in the car. Only thing we have added is Llumar UV protective film on all windows (including sunroof), film is fully transparent on front doors and 40% less light through rest of windows; only window without film is windshield as that is protected from factory, an extra remote so driver's seat can automatically adjust to 3 persons.
Answer: Mark Levinson audio system is not only available to F-Sport. In my opinion it should be in all cars. It is absolutely great.
