Hi Emilio,
I realize you're looking for a good mechanic in the Bby / NewWest area but if you're willing to drive a little further, I would strongly recommend \"Lou's Work Shop\" I'm sure a lot of people have at least heard of him, if not taken their car to him.
His shop is in N .Van but it's definitely worth the trip. His number is 985-3133
Hope that helps
Cheers
Tom
