[QUOTE="Otto"] I'm looking at the Accord coupes, and 3 models out of 4 have moon roofs. Are they for ventilation, or just for show? When open, do they make a lot of wind noise? Do they leak a lot?[/QUOTE] I always have the shade open (except when parked on warm/hot days) even if I don't always open the glass. Don't know if I could get used to not having one after 20 years and 3 Preludes (84, 90, 99). As far as leaking, occassionally check that the drain tubes do in fact drain by pouring a little water down the 4 corners (at least the ludes have 4 drain tubes). Check that the water leaks out from the body, typically behind the wheels somewhere. I had to clear the rear tube outlets (rubber nipples) with a small screwdriver on the 90 Prelude after taking a surprise shower upon the first turn after work one day. There was just a very little debris plugging the outlets, but obviously enough to fill the rear tubes and inner metal tray while the car was parked slightly uphill during an all day rain. Other than that surprise, I've only had a few drops in the inner tray on all 3 cars after a rain or wash. If you plan to use roof racks, check the mounting and clearance. I never had problems with Thule racks on all 3 cars (critical positioning on the 84 since the radio antenna from the drivers pillar had to thread its way past the roofrack crossbar and short roofline adapter. And, the salesman did wonder what I was doing with cardboard cutouts, rulers, and tape measurers before I actually bought the 99-the first moonroof for me that slid up and out instead of down and in.
