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’ve serviced our two GMC trucks at McCaddon’s for over 10 yrs. and always work with Dave Singh in service department. He has helped us several times with suggestions which saved time and money. We trust his experience and forthright advice on maintenance issues. We have never had any problems there. Thank you Dave for your help.
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.
I had wonderful service at this dealership and wanted to see if the system really worked.
Another wonderful experience at McCaddon in Boulder! Zach went above and beyond on this transaction. Thanks!
Amazing fast and friendly experience, they went beyond the normal to make my experience fast and everything was explained or portrayed to me to the best of the ability and knowledge. I would definitely recommend them to others and will be doing more business with them in the future.
Jon Beery and his service team has always been courteous and professional in handling the care of my Cadillac. My husband and I recommend and appreciate their hard work. Tonia Canipe
The best customer service and expertise I have ever experienced. Truly amazing
Excellent customer service
Do not hesitate to buy your next vehicle through McCaddon. Their team is a professional, no pressure, considerate group that will bend over backwards to help you find your next vehicle. Their service department is probably the best we have ever used.
Excellent customer service!
excellent treatment with both sales and service. Jon Berry in service is a good as they get. great explanations and follow-up. Listened and acted on my needs. John Clark is a long time sales person, low key, yet knows his job. Great follow-up and very responsive. Had everything ready to make a fair deal on a purchase and trade.
Always informative, helpful, kind and accommodating
I was traveling on vacation from Missouri when I experienced an issue with my GMC Sierra 3500 which I was pulling a travel trailer. GMC Customer Service was calling dealerships in the Denver area. The first 4 dealerships said it would be 2-3 weeks before they could get me in. Obviously, this would not work for someone who is stranded while on vacation. Then customer service called Erik Wolkan at McCaddon GMC in Boulder. Erik said to send me his way and they would get me in as soon as possible because he knew what it was like to be stranded on the road. Erik and his team took care of everything, they gave me a courtesy car and even let me set up my camper in the back lot of the dealership. Erik Wolken is the best example of a Customer Experiance Manager GM could ask for! The following morning they were able to get my truck in early and quickly discovered the problem was a simple update to the computer system. Erik and his team got me back on the road by noon that day. I will be forever grateful to the members of the McCaddon team that worked so hard to get a traveller back on the road. Thank You!
One stop shop for all my Cadillac needs
I live in Virginia and bought a 2021 bright blue Canyon from McCaddon. It was the only one in the country that matched my criteria and Joe did an excellent job helping me through the process. He answered all my questions in a timely manner and made sure I was getting what I wanted; even with me only seeing pictures of the truck. Joe was very knowledgable about all the features and even had very helpful suggestions for the spray-in bedliner and cargo hooks. Thanks to the finance department also for doing a great job. This was my first new vehicle and feel fortunate that Joe answered the phone when I called McCaddon. I didn't think it was possible to buy remotely and contract a transport company to deliver it to my front door but Joe and the McCaddon team made it happen without a single problem.
I give them a top rating. Next time I look for a car, I will contact them! I had a terrible experience with Suburban Cadillac of Costa Mesa. they sold the car out from under me. after 3 days of me asking to put a deposit on the car, they came back with an email. not in person and told me they were not selling me the car. You need to look into this dealership. some dealerships are charging a $1,500 fee for the chip. McCaddon doesn't and has low fees.
Joe was an amazing resource during my recent purchase. He was patient, knowledgeable and helpful throughout the transaction. Any questions I had were answered fully. I would heartily recommend Joe to anyone making a new car purchase.
Worked with Joe Cleland and he provided excellent service. He took the extra time past his scheduled shift to make sure I understood the many features on my new car.
