I usually get my work done at OTS Auto repair. It's off of Pond Springs Rd.
Also, my buddy Clint fixes all of our friend's vehicles when needed. He works on custom cars during the day. I have no idea what he'd charge though. He definitely isn't stupid pricey. He lived in Cedar Park.
I've been real happy with Bobby (owner) at Oak Knoll Automative on Jollyville next to Bucks Bikes. He always seems to genuinely care about the car and takes time to explain what he's doing and why.
