Honest, affordable, helpful. I’ve dealt with a lot of auto shop bamboozlement as a woman, so it was refreshing to have a very positive experience where the problem was explained precisely, and dealt with promptly without any hint of condescension. Thank you!!

The Duffy's team come thru again. I've used this shop since they were at the old location on University Blvd. I've always found Bryan to be honest and fair with anything they have done. You just can't go wrong choosing Duffy's as your 1st GO TO for car repair.
