I just bought a GLS TDI with leather seats and sunroof. I am loving my car more and more everyday. Being a diesel engine, I get great fuel economy! Other the engine is noisy on the outside, once you get in the car, it sounds like a normal gas car, the car may be even more quiet at crusing speeds of about 60-70 miles/hr. Only one thing I don't like about the car is the cup holder. They get in the way of the radio and CD player!! Otherwise, I would highly recommend buying this car!!
