I've always had my VW Golf serviced at Buttera. For me I'm glad that they know what they are doing because I don't have to bring my Golf to a VW dealer because the closest one in probably the one in Bellevue.
To the one who had the experience of the one who had the coolant leak issues, it is possible that you really did have two separate coolant leaks.
I used to own a VW Rabbit and did all of my own repairs, talking to the mechanics at Buttera, I've come to appreciate their expertise. I've always been given options and never charged for diagnosis. They've even steered me clear of expensive repairs that I was convinced I needed and did a simple adjustment for free.
I've also had my Audi A4 for basic service and they have done a good job.
