2008 Honda Accord
"I visited BAY on 2/1/20 for an alignment issue created by the BMW dealership I went to this past Oct. I was greeted by Keith who was more than happy to open the garage earlier than they opened. He explained everything involved in the alignment process and best of all they have the state of the art equipment required by BMW to do the work properly. Suffice it to say they corrected the problem. And the most pleasing part is that the steering wheel is actually straight. Take it from a guy with OCD, a straight steering wheel is beyond important. As soon as the maintenance warranty expires with BMW I'll be bringing my car to BAY. And they are located 35 minutes from my house."
"Went in for a pre purchase inspection. The car passed and they explained why and provided a detailed report. Good quality and friendly service, reasonable prices, definitely will be going back for future service needs. I recommend all to come check it out."
"I have been going to Bay Diagnostics for close to 15 yrs. I have an outstanding professional relationship with Jordan. I have ALWAYS been treated fairly and honestly by Jordan & staff. You don't find too many honest & decent mechanics today. I've continued to go to Bay Diagnostics because I feel as though I'm not going to be sold something unnecessary or not needed."
"Great service, super knowledgeable and friendly staff. Other customers who were in the lobby when I arrived said they had been coming here for years, and I see why. Took great care of me and my Mini Cooper. Will be back!"
"Brought my 2015 Audi allroad in recently. Keith and his team were professional and did outstanding work, and pricing was considerably better than the dealer. Strongly recommended."
