I'm not sure what you mean by weathestripping, exactly.

Yes, you can buy it all new.

The front and rear window seals will cost you about $50- $60 each for non-mercedes stuff. The window scraper seals are about $15 each. The door seals are about $50 each.

I have done all of these exept the windshield at this point. The rear window is not for the faint of heart. I'm pretty sure the windshield is similar. The scraper seals are easy- the door seals are a PITA. I just did them today.
