Just bought a copen - advice please...


I've just bought a copen and previous to the test drive I had with this car, I've never had a ride in a copen before! I really do love my new car but just wanted to ask a question...how noisy should the drive be? There is a significant amount of rattling when I drive and I'm unsure whether this is just the nature of the vehicle due to the fact that it is convertible or do i need to go and get the rattling fixed?
Any advice or hints/tips would be most appreciated.
