Les Costales, the GM of Luxury Auto Works used to be my service advisor at BMW of Austin. He's always been extremely knowledgeable, thorough, and above all, honest and friendly.
There are some shops that have great prices on some services, but can't do some of the more complex services. I had a well-known shop in Round Rock take my oil and filter, and I found out later that they actually didn't change my oil.
My X5 needed a lot of work, and I wanted to find one shop to do it all. From a transmission fluid replacement for the notoriously difficult to drain/refill ZF8 Automatic in my 2011 X5, to diff /transfer case fluids. Les and his team got it all done, and I was even given a loaner for the duration.
Just recently, I took my X5 in to get the front brakes done. While lifting it up, the car started leaking coolant everywhere. After a bit of diagnostic work, Les discovered my expansion tank had bitten the dust at 93k miles. I was given a loaner, and the next day, the brakes, and expansion tank were done, along with re-installation of underbody panels, clips, and screws that a previous shop in Houston carelessly threw away.
There are other shops in Cedar Park/North Austin that offer good service, however for a shop that can handle everything from an oil change on up to a full engine rebuild, I trust Les implicitly with our MK7 GTI, 135i, and X5.
A shop's cleanliness/organization reflects on the quality of their work. Do yourself a favor and check out the shop Les runs - He'll gladly give you a tour. While I've got some relatively "cheap" European cars, if I had a Lamborghini, Ferrari, Bentley, Alfa, or similar, I'd not go anywhere else.
When I first brought Les my first BMW, a 2004 330xi back in 2011, I didn't know him from Adam, and BMW assigned him to me as my SA. When I picked up my second, a 2008 X3, I saw how he fought to get work covered under warranty and how he made sure the techs got things right before calling me to pick up my car. He didn't have to do these things, but he earned my trust, which is why I continue to trust him. The cherry on top is that he's passionate about the cars he works on.
Thumbs up.
