The Porsche Panamera is a four-door sport car manufactured by Porsche. That day, I saw this monster in the car park, it's sound damn loud, I am not sure whether this is the original Panamera's sound? or the sound after modification?, but, unlike some car with modified exhaust which sound loud but noisy, this sound loud but nice.
I like the design of the Panamera, which is the most beautiful car the Porsche have made. (exclude the GT1 and Carrera GT)
