newbie with few question

[tdog]

Hi all, I've finaly got my 97 boxster with only 19500 miles, and what a experience has been for me especialy with the unbelieveable weather we have in Seattle. The previous owner has done excellent job upkeeping the car, everyone thinks I just bought it new from the dealer. Few question for some of the experts here. Even though the pervious owner just got the top serviced, last few days when I close the top, the top won't close all the way even after the lights gone off, it's about less than a inch gap between the windshield, I have to force down to close it completely, is there any quick fix for that??, currently, 18inch carrea wheel is on the car, but I saw some thead that 18inchs are bad the car? is that true, finaly, is the coil for heated seat builded in? can I just buy the hareness, and switches to get heated seats?
Are there any boxster owner in here from Seattle? I would love to see what kind of mod or hack u have done to your car
