Get in my car this morning and am greeted by an indoor pool in the space where my backseats were. Water is also pooling into the spare tire tub in the trunk. I am missing about a quarter inch piece of molding on the rear window, which could be partially responsible for the leak. I've never had to deal with this sort of problem on any car, much less the 240. Are there common leak issues among 240 coupes? How much of a pain in the ass is it to reseal a rear window? Are the rear window moldings still available from Nissan?

And my front windshield moldings are shot as well...are these still available for purchase? Any ballpark idea on how much these cost?

Sorry about all the idiotic questions. Just trying to get this car sorted out. I appreciate the assistance everyone has given me thus far.
