Oh yeah, and just to add. I had a 1997 VW GTI VR6 that Auto-Up windows AND sunroof. You could also roll them up or down with the keyless remote, now that was cool. Oh, and for safety, it did have the auto-reverse feature if there was a obstruction in the window or sunroof opening. That was about the only good thing about that POS.
Actually there are alot of cars that offer the remote roll down windows. All Honda Accords that have factory keyless entry since 2004 have the remote roll down feature. You just can't roll them back up without getting in and putting the key in the ignition first. Acuras, BMW, Audi, VW, Honda, and I'm sure a few others have this feature now. Hell the Jaguar XK-8 convertible that was released in the late 90's can even put it's top down remotely by turning the key in the driver's door. If it was equipped with auto windshield wipers, it could even be programmed to put the top up unattended if it started to rain. I've also seen other cars that can do the rain thing with an open sunroof.
Okay, I'm getting carried away with my useless car knowledge. I'll stop...
