Wow! It’s always so difficult to find a trustworthy mechanic and not feel like you’re getting hosed. Marengo Auto was upfront with me. Not pushy at all and gave me options towards what I needed done. I have already recommended them to friends and family. Thank you for the efficient, timely, and affordable work.
