1. I live in L.A. so I cant help you there.
2. There is no "fix" that I know of short of buying that entire cladding section.
3. Silicone spray regularly the tracks of the windows. For a more permanent window fix, check the "how-To's" section of this forum or do a search on "window fix".
4. This is a problem many have complained about, however for most, the movement has been so slight that you dont notice it until after a number of days. I think you would need to find a really nice dealer to replace the seat, and only if it was still under warranty.
5. If you do a search on "squeaks" you will find others who have the same problem and the fix.
6. Covered under warranty, they should replace the whole headlight assembly. I have heard from several that certain bonding agents work better than others.
7. Dont know that one.
