Has anyone had any luck with upgrading into a Tesla on a PC reservation? Did they charge the $25 etc/day or is it a YMMV thing. Currently have a good rate on a rental, I can upgrade via the website for about $300/12 days, but Im cheap, what can I say lol. Its not "vital" I get the Tesla, just reading the LAX reports and my own personal experience is PC is a real crap shoot there, most of the time ending up on the wrong end of that one.
