Bought the E320 CDI to replace 04 BMW 530i. The difference in quality are amazing, for a $50k+ car the BMW is cheap and tacky inside. MB feels like it costs a lot more. Fuel consumption made me get the diesel, after test- driving both the gas and the diesel. The torque is stunning. Averaging 33mpg combined so far.
Quality, equipment, fuel consumption
Cruise control adjustment in 5mph increments - only thing I miss from my BMW.
