We’re very pleased with the service we received from Joe and how personal he was to make sure we knew our vehicle. A very nice group at the dealership. Thanks again. Kevon and Fritzi.
We are beyond grateful to have had Joe by our side through our recent car buying experience. He was extremely knowledgeable about the current automotive landscape and ultimately landed us the perfect car for our family. He gave us the space we needed to make our own decision on this big purchase but also provided super helpful input & insights to aid the entire buying process. Not once did he feel like a pushy car salesman and instead approached us in way that created trust and made spending time at the dealership fun (Justin in the finance dept was also great and made that piece super seamless!), not stressful - we will for sure be calling Joe when we’re ready for our next car!!
Very friendly and inviting, salesperson was honest and knowledgeable overall I had a great experience and would recommend.
Always a great experience here! Efficient, friendly service every time. Thank you to Dave Singh for taking good care of my whole family!
Joe was great to work with! He made this process easy. He was also great at explaining all the details of my car! I would definitely recommend Joe, and your dealership to my friends and family!
This is the Best dealership I have worked with! Zach Brick and Justin Gasman are amazing!!
Joe Cleland is the absolute best! We were so happy to buy our new Cadillac from him. He is an excellent communicator and was with us every step of the way. He was also so generous with his time, making sure we had all our questions answered and showing us all the features of the car. Additionally, he was never pushy but always realistic, honest, and helpful. We would recommend Joe to anyone!
Super easy and a pleasant experience. Joe Cleland is amazing. Made it easy no pressure in buying.
Walking in everyone was so nice and inviting. We definitely felt like they cared about our wants and needs and not just a sale. Joe was a great salesman and really made us feel comfortable and not pressured. He was knowledgeable and friendly. Justin in finance was friendly and very funny. He kept the process quick and lighthearted. We really enjoyed our buying process.
Just like family when you walk into the service center. They always treat you well and do the best they can for every customer.
Dave Singh has always taken excellent care of our car needs. He's prompt getting the car in for service and goes the extra mile to make sure we're driving a safe and clean car. Thanks Dave for the free car wash!
My pick up had an oil leak which 2 dealers tried 5 times to fix. Dave checked me in and problem solved in short order...I'm very happy with the service and courtesy of everyone at the dealership...especially Dave and the mechanic which fixed the problem. Past dealings with McCaddon have been pleasing when purchasing a pick-up...tom neal
Service at McCaddon was outstanding! Dave Singh and the service team were professional, timely and I am more then satisfied.
Outstanding attention to detail in sales process, friendly and knowledgeable people. Full transparency in financing arrangements. Could not be happier with the experience.
One call had me scheduled and in the next morning along with the issue fixed plus my bill was LESS then the quote
Working with Dave Singh was a very pleasurable experience; I would highly recommend getting your GMC serviced at McCaddon GMC
Dave Singh did a very good job getting my vehicle serviced today. Only thing missing was the door for the wash bay not working,so no wash for the vehicle.
Service was excellent during my visit with them very courtesy attended and they fix my car the next day thank you to all for your services especially Jeff Hale Thank you
I was traveling and had problem with my GMC Sierra, came into dealership during holidays and they provided my with rent-a-car and most importantly got my vehicle fixed right and able to continue vacation while also knowing that I would make it back the 1000 miles to home. Joe in service, did a remarkable job getting everything handled. If I was a resident of the area, this would be my GMC dealership to go to!
Dave Singh really went above and beyond to help me out when I really needed the help. Dave made it easy. A job well done.
Nice People! Clean Facility! Easy Location to get to! Dave Singh is an amazing employee in the service and department and always goes above and beyond to make my experience an easy and enjoyable one! Highly recommend this facility!
We take both our cars to Jeff Hale at McCaddon. He is straight forward, friendly, and good at following up with updates.
I take all my cars to McCaddon for service even the foreign made models. Jon is simply the best service guy around. No BS just great service. No pressure just the truth. They always wash the car too! I am a fan for life.
I always get excellent service at McCaddon. This particular service wasn't for a Cadillac, but for my Corvette.
We have serviced our 2 GMC pickups at McCaddon for over 10 yrs. and have never had any problems. Dave Singh has helped me on warranty and scheduled service over the years and not one problem. His advise has saved us time and money. Like his pleasant personality. We’ve used the ride service without any issues also. We did not buy our pickup there but would not take our vehicle anywhere else for service. Thank you Dave and McCaddon.
