I just purchased a new S80 and want to take great care of the car. I would appreciate your experience/advice on a few concerns:<BR>1) Do you recommend a car cover? I have heard good and bad about car covers. My car is not garaged. If you do recommend I use a cover, which type? What about the one Volvo lists on its website?<BR>2) What cleaner do you recommend for washing the car? Do you recommend waxing? If so, with what brand and how often?<BR>3) How do you clean/maintain the leather interior? the dash area and woodgrain?<P>Thank you so much for your assistance.
