Interior is very disappointing for a premium car, with plastic everywhere and seats that (though comfortable) have peeled and discolored (seats were spruced up and refurbished by dealer when car was just 2 to 3 years old). Controls and switches etc. have a complicated implementation including the infotainment system that is terrible compared to a BMW for example, of the same year."
