I just wanted to thank Rob for getting me out of a difficult jamb. My battery was failing, which required multiple jumps, and Rob was able to get me into service immediately even though his schedule was quite full. Rob had the battery replaced within 30 minutes of my arrival. I have never visited Fowler dealership in the past but will make it my go to place for future services.

Excellent communication and efficient process
For my recent service appointment, I was impressed with the excellent communication throughout the process using text messages. Nick was on top of everything from the moment I arrived for my scheduled appointment. Getting a loaner vehicle was quick and easy. After the inspection, I was able to review the recommendations and costs and then approve the services I wanted. The service was completed sooner than I anticipated, and pick-up was a breeze. Many thanks to Nick and the service department for a job well done.
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

I thought I was going to get a lower price for my trade
I thought I was going to get a lower price for my trade in. Lexus of Fredrick was the first Lexus dealership i have been to that did not low ball me on my trade in. My whole experience with Lexus of Fredrick, was outstanding from beginning to my purchase of a GX-550.. I have gotten three emails and a phone call from employees of this dealership inquiring about my satisfaction with my new vehicle, very impressive.
The vehicle was a good experience for the first ti
The interior was very comfortable and the color combination made the experience very nice , was very surprised by the power that came from the engine

Bought 2 cars. An Audi Q5 2 years ago and a BMW X3 m40i this year. Outstanding service on both vehicles. Owen was my sales guy on the BMW. He was knowledgeable, friendly and very helpful. I left some keys in my trade in. He recovered and mailed them to me. I recommend Peak Kia, Littleton.
Perfect for the family of 6 like me.😍😍😍
I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

Appreciate the honesty and transparency regarding the vehicle inspection and what work had been done on the car. Jessica was great at keeping me informed of where she was in the process and what the next steps would be. It was a pleasantly quick but not rushed buying experience.
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

Amazing Experience
I was so grateful for how kind and caring the staff here was when I went to go for my very first car purchase. I was incredibly nervous because I'm only 23 and I've heard horror stories about car shopping experiences for women, but they took such great care of me! They answered all my questions and were just genuine and honest with me throughout the process. The manager Chris gave me the validation and confidence I needed to finalize my purchase. I will 100% recommend this dealership to all of my girl friends and family because of the amazing experience I had here! Thank you Boulder Chrysler Dodge Ram for all your help in finding my dream truck!

A GREAT Dealership
This is a Very Pleasant and Trusting Family owned Dealership. They try hard to satisfy the customer's needs with the right vehicle. They have ALL the vehicles inspected and they are available with a Warranty included in the monthly payment. I have known this Family since the mid-nineties and done business with them all these years making the car buying experience FUN !
3 month review
I purchased the vehicle off of a lease in March with 60K miles. Overall I am pleased with the purchase. For the size the SUV is very nimble. The surround camera is a must. On a 350 mile round trip my 5'6" daughter-in-law had no issues sitting in the third row. I put the car seat for my grandson in the 2nd row drivers side because lifting the 2nd row back after 3rd row access is cumbersome and heavy on the drivers since you have to lift the middle seat as well. MB you have to make the 2nd row power back to upright position. Adaptive cruise control is outstanding but keep in mind you have to get the Driver Assistance package to get it. Harmon/Kardon surround sound is very nice. My big complaint is sometimes at speeds above 65 MPH there is front vibration. Does not happen all the time, sometimes I can cruise at 80 MPH and feels like I am sitting in my living room. I think it may have something to do with the Pirellis, I plan to switch very soon to Michelins. A very classy, roomy and comfortable SUV

Lindsey and Prestige Audi are 5 Stars!!
We moved to Colorado from the east coast. Needing a vehicle for the CO weather, the Q5 was the perfect vehicle to meet our needs. Lindsey was so great to work with. During this challenging time in purchasing a vehicle, she was knowledgeable and patient with us. We worked with Lindsey to identify which Q5 was most suited to our taste. She researched and worked with another dealership that had the exact Q5 we wanted. We are beyond excited with our new vehicle. During our vehicle search, we visited several other Audi dealerships, but Prestige Audi was by far the most accommodating. Based on our experience at Prestige Audi, I do not see us going anywhere else when purchasing a vehicle in the future.

Great Service and a Pain Free Car-Buying Process
My wife and I were looking to replace a vehicle; online browsing led us to several choices from Drive N-Motion. My wife visited the location over lunch one day and met Zach. She left with a strong impression and Zach was quick to address our numerous emails. Throughout our search, Zach was personable and knowledgeable. We set the pace for our car-buying experience; Zach always made himself available but never pushed us to move forward. On numerous occasions, he adjusted his schedule to work with my wife and I. As we narrowed our search, Zach continued to provide us with additional options. Once we had sufficiently narrowed our criteria, Zach even searched Drive N-Motion’s incoming inventory and made available additional vehicles which fit our budget. Zach went above and beyond to serve us. He and Drive N-Motion took the car-buying process and made it as pain free as they were able.
Almost perfect for luxury family truckster
Owned this suv for 15 months purchased certified preowned with 33k miles and about half the price of new. The truck has only two issues to note but otherwise rides, drives and in all other respects is far and away the best automobile I’ve owned - which saying a lot for an old guy. The standard tires are nearly useless in snow and ice and we hope an aftermarket replacement will address the issue later this fall. The more annoying downfall is that although the ride is otherwise amazing, the truck handles sharp bumps very poorly - almost the feeling of a car with workout struts. I have had the struts replaced under extended warranty but the improvement was marginal. For most drivers the suspension issue wouldn’t likely be as much an annoyance but for my fellow ocders, be warned. I would buy the truck again, however.

I had a fantastic experience at this dealership!
I had a fantastic experience at this dealership! Griffin was my primary contact throughout the sales process and I cannot thank him enough for the wonderful assistance he provided me. This was my first time purchasing a vehicle, and upon hearing about the negative experiences people have had at dealerships in general I became nervous about the process but Griffin alleviated my nerves quickly. He was not your typical pushy or overly persuasive car salesman, rather he was respectful, attentive, and patient from beginning to end, especially when answering my questions, teaching me how to navigate the technology of the car, setting up the Mercedes app and so forth. Not to mention that due to my initial nervousness I had brought my family along and Griffin also took the time to answer their questions, which I appreciated as I know addressing the comments of multiple people at one time can be a lot to handle. The financing director, Marco, also exhibited the same traits during the purchasing process which I greatly appreciated. All to say, I would highly recommend this dealership as well as Griffin?s and Marco?s assistance!
