The guys at Stonum are always pleasant and knowledgeable and answered all of my questions. However, in this age of Covid when I was there yesterday many of the front desk staff are not wearing masks even while coughing and sniffling. It does not engender confidence or comfort when I need to wait for my vehicle while sitting in the lobby. This makes me hesitate to take my car back To them for service unless and until Covid is over. It feels disrespectful to the customer. Unfortunate.
I'm a long-time customer, multiple-time reviewer. Most recently, I brought in my 9-yo truck for a check engine light issue. They quickly diagnosed the problem to rodent damage to some wires. Prefessional, prompt and trustworthy. I also bring my work cars here for service. I hightly recommend Stonum Automotive if you want to keep your vehicle in the best possible shape.
Amazing service, good information and worked around a few of the things I could do like changing the wiper blades, etc. No pressure, honest. Peter is great, they have really well trained down to earth techs.
Great job! I didn't have the time to schedule an appointment, so we just dropped the vehicle off over the weekend and on Monday morning they gave me an estimate, ordered parts and got me going by Tuesday noon. Thanks again Leon.
Oh boy what can I say about these guys, well first off they are all very nice gentlemen and they listen to you and not treat you like you don’t know what’s going on with ur car. I have a 2013 Ford Mustang that has electrical problems and she broke down about 5 mths ago and I went to 3 mechanics telling me replace this and this and of course I did and I was now 1700 dollar deep and when it wasn’t fixing my problem I about gave up on fixing her cause no one would listen to me when I kept saying it’s a ground issue, But that’s when I found Stonum automotive and when I walked in there they were all so inviting and listened to me and wrote down what I thought was the problem and 2 days later I get a call telling me to come to the shop so we can talk and I got the best news possible and it was that my mustang was finally fixed and working. I’m being serious when I say this but this will be the only place I take my car now, they are honest and sweet guys and very professional. Thank you Chris and to everyone else there. I will tell everyone I know about you all. Thank you for getting my mustang back up and working
Stonum always does a great job on my vehicle. Jace the technician did a thorough inspection & found preventative things to do to keep my car going strong! I trust this garage as a female not know much about cars, they explain everything clearly. I highly recommend Stonum & Jace to anyone.
Inspire salon continues to amaze me. In the face of COVID-19, they take precautions to ensure that guests and staff are safe while still providing top notch customer care. The salon is impeccably clean, every single person was wearing a mask, and they were very strict about max capacity of no. More than 10 people in the salon and less whenever possible. This salon should be the leader in how to reopen a business utilizing very strict precautions while still providing a service and an opportunity for small businesses to succeed and for professionals to make an income doing their craft. Never been prouder of this business.
