On the more positive side, as stated my 2 old XM's don't leak but the CX does and the 2cv well......

On the more arrogant side: thanks to the good old youtube I assisted in fixing a 2008 BMW X that was bought for 95000 euro's and needed some soldering in it's electronic bag of niceties.... And if there's anything I don't like, it is just that.... (electronic failures, BMW's, soldering) But success felt sweet and the owner of that car liked my XM so all good now! Happy days! 7 seconds from 0 to 60 miles for a 2 ton car, not bad!
I hope you won't get the opportunity in a long time to test your now waterproof sunroof.
