Marc was very helpful and friendly in servicing my truck. He's timely--even finished earlier than I expected... Professional service from a family-owned shop.

Marc was very good at communication. Always let me know what was going on. He completed the job much faster than I had anticipated with a complete engine rebuild. His pricing was fair and reasonable.

I'm writing my review a few weeks after the actual repair because I wanted to use my repaired boat before giving a 5 star review. Marc was willing to provide a general estimate for what he suspected might be the issue, which I appreciated. He quickly got to my job and made a thorough repair. His shop rate was less than the dealer. He sent me a video showing that the repair was completed, so good communication (I still wanted to test it in the water). I will use him again for boat repair.

Marc did an amazing job working on my truck. He was upfront and honest about the repairs that needed to be done. And didn't break the bank. And he stands behind his work. I would recommend him to all my family and friends.
