Multiple vehicles purchased and ZERO issues. A+
Great selection and good prices. I needed a van for my business and I bought 4 from them out of state. When I picked them up they were ex aptly as described. And all.of them made the 550 mile trip back no problem. Very satisfied and they took care of me like family. I asked them to please make sure my crew would make the the trip back without breaking down and they did. Will be buying more vans for my fleet and this time I will have them ship them since I can trust them after this experience. Out of 20 years in business and buying vehicles they have been the best dealer I have dealt with so far
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

I spent a couple of weeks searching online for just the right Cadillac at just the right price and my patients paid off when I found Arnie Bauer Cadillac, and Rowland Laird. Rowland made the entire process, smooth and simple. He had the car detailed and inspected and ready for me when I arrive for the test drive, and was very helpful and professional the entire time. The finance department was very helpful and made it simple to work with my credit union to complete the purchase. I will be going back to this dealership again when I’m ready for my next vehicle in the future.

Thanks Marcin Kenny & Jimmy
An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free. My salesman Marcin and manager Kenny went above and beyond for me to locate the perfect vehicle to fit my wants and needs along with staying in my budget. Jimmy also got me in and out with paperwork. Would definitely recommend all family and friends! Thanks Rizza GMC!
