Greetings all, I bought #693 (a Glacier Blue 2.0) from a good friend. I have borrowed the car for extended periods of time in the past so my garage was already set up to charge it and I'm pretty familiar with the car. A/C works great even in Los Angeles summer weather. Condition overall is basically perfect. Well cared-for and low miles. I'm glad to have found this forum as it is very active and people here really know their stuff. I have some questions I hope some of you have thoughts on... I was wondering if any of the seven Service Centers in the greater LA area are better than any others, particularly with respect to Roadster maintenance. I heard mention about how some SC's have "Roadster experts" which suggests that some don't. I read in another thread something about an HID headlight upgrade from Tesla. Is that the best headlight upgrade compared to the aftermarket LED headlights? Also, what do people do about the moisture that can accumulate inside the headlight covers? I might want to upgrade the stereo head unit at some point, going from the factory single DIN to a double DIN. What upgrades are popular for head units? Thanks, and any other tips you think I should have would also be appreciated.
