Good advice in this thread. Yes OP (how's that coding going for you, btw?
), I'd definitely check out the Tejas Chapter events. The Berli's and BBQ event should be pretty interesting, and I'm actually coordinating the Bluebonnet Drive in March.
As for service, yes BMW of Austin is an amazing place. The facilities themselves are incredibly nicely done, and where else have you found a dealership with a movie theater? Yes, seriously, complete with soundproofing, La-Z-Boys, and a ~106" projection setup fed by a 500-disc Blu-ray player that allows you to choose what to watch while you wait. And the employees there are unbelievably helpful and polite -- not just the SAs, but the techs too! I once had an SA walk me from Point A to B and he couldn't accompany me all the way but clearly pointed me to the door I needed to go to and then radioed ahead to an employee at said door asking them to make sure to get the door for me!
All that said, I have no idea what they charge for work done outside of warranty/Ultimate Service. If you need an indy recommendation closer to Central Austin, check out Flamingo Automotive. I wrote a review for them on Yelp so I won't regurgitate all that here, but you can read it here:
