ORIGINAL: BootCamp
Both my Cruiser and my wife's Charger R/T have sunrooves...... we rarely use them. Neither one leaks....my Cruiser is an '01, the Charger R/T is an '06.
No sunroof on my Challenger - windows down, or AC on.
We're talking in the very long haul, many years down the road. The seals will eventually get bad and it will eventually leak. It's also like power windows. If you use them a lot they will eventually have problems with not wanting to go all the way down, not wanting to go all the way up, not sealing properly, etc. The same issues will eventually happen to a sunroof depending on how much you use it.
