I started the search process online.
I started the search process online. When I found the truck I wanted, Nikki (Courtney) and her team were able to work out the deal I wanted. When I got to the dealership it was all ready to go. No surprises. They also let me know about an additional bonus $500 off using the GM Card toward down payment. The finance guy was also very good. He told me about warranty options. We were not able to spend any more for an extended cuz we hit our budget limit but he was able to get us one that was basically free after the $1250 incentive offered with it. Everybody was nice. Nobody was pushy. All the text replies were quick. I would for sure go to Autonation again.
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!

Tom Anderson and the service department at Henry Brown
Tom Anderson and the service department at Henry Brown always do a stellar job for my Yukon. I've been going here 8 years and each time I receive friendly, thorough, and transparent assistance. Joe Stenz is stellar and makes getting my truck serviced a breeze. I was able to work with Wes recently while Joe was out, and I recieved the same help I've come to appreciate from Henry Brown which is a testament to how Tom runs his department. I highly recommend visiting Henry Brown for all your needs.

Tempe Honda made the buying experience low key, no sales pressure, with a professional team of car enthusiasts who made every effort to explain the features of my CR-V. My sales expert, Tommy K, was the most knowledgeable and friendly associate I have had the pleasure to work with buying a car. Highly recommend this dealership, Tommy, and his sales manager Danny K!

Noticed some of the reviews on here for Rollit motors are not good. My husband and I have purchased two vehicles from this dealership and we only have good things to say. We worked with Jaime the two times he was great honest, available and offered great customer service. The two vehicles purchased are still in perfect conditions. I highly recommend.

I purchased a pre-owned Subaru which had a couple issues. Bill Luke's service center took care of everything promptly. Brad and the service center staff were great. Altogether, from first looking for a car with the sales staff through the final service appointment, I have only the highest regard for Bill Luke Santan.

Honda Civic
Super impressed with this dealership. Not at all what you'd expect in a "city" dealership. Spotlessly clean, open, bright . . . and friendly. Plenty to choose from. Didn't feel pressured at all. And they were very flexible (I can be kinda demanding). Great on the price. Highly recommend this store! i know some people scared about salvage but you fill comfortable when they let you to take it to your own mechanic shop or local dealer to check, they also give us warranty as no cost.

Shop smarter Not Harder
To me these reviews all sound like everyone wants what they want this is a business that’s selling used cars a tip to help new buyers. You are given a 500 mile or 15 day warranty take the car you buy down to the original dealership or any mechanic have them do a over all inspection if anything is wrong with the car that the warranty covers take it back to the place you bought it from and they are legally obligated to fix it at their expense not yours because it falls under the warranty also make sure you buy GAP INSURANCE AND ANY OTHER EXTENDED WARRANTIES REMEMBER THIS IS YOUR MONEY AND INVESTMENT!!!!! Hope that helps anyone out on here or anyone looking for a car. I AM NOT A LAWYER & THIS INFORMATION IS BASED ON A PERSONAL EXPERIENCE…..
