BMW Austin is awesome. If you need a BMW dealership I would use Austin and see a man named Charles Bellinger service advisor his number is 512-343-3531. I am from Killeen and in a pretty big MFEST club and we all go to him... Also in Round Rock my buddy T'erre just opened a shop called AutoOne (http://www.facebook.com/AutoOneTx?ref=ts&fref=ts
Good example of why he is the man. I have a blown turbo due to waste gate failure. I brought my car to him (Its full bolt on) and they gave me a rental for a week and came the conclusion its the turbo... Told me to revert it to stock and they would fix it under the turbo warranty. I feel like most shops would tell me to bad since its heavily modded and flag me with BMWNA.
