i just got this 560 sel and i had a few questions about it. it has 75,000 original miles, but it has a rough idle. when i take it out of gear the idle smooths out. also the outside temp gauge doesn't work. and the sunroof only goes up about 1/4 in. and there is a clanking noise from the drivers side rear and the rear sags a little. i got a good deal on the car so i would like to fix it up and keep it!all the help that can be given would be helpful
thanks
