I'm considering the purchase of a '03 E55 with a Panorama roof and solar option. Has there been any problems with this roof option or can anyone offer any comments, pro or con.

 

I haven't heard of any problems with it, and I've had mine for a few months and the only complaint I have is that it's pretty loud over 50mph when you have it fully open. But if it's in the "vent" position then it's no louder than a normal sunroof.

All in all, I highly recommend it.
