Great experience leasing a jeep compass from Matt!
Great experience leasing a jeep compass from Matt! Very honest, efficient and helpful! We had them pull up a couple different models from the lot and they did so outweighing pros and cons of each!
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.

Seisho was outstanding- knowledge; responsive; engaging.
Seisho was outstanding- knowledge; responsive; engaging. He stayed in touch with me over the past several months as this particular car was not available. Once the car I was looking for showed up - he called me immediately!!
Love it so far
Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

I am very impressed with the used car team at Gebhardt.
I am very impressed with the used car team at Gebhardt. Kris was very knowledgable and friendly, responding to all my weird questions. Ryan managed to find me a better interest rate than my own bank. Tom gave me a bit of history of the dealership - one of the few remaining family-owned dealerships in Colorado- and showed me his beautiful classic car. I’ll be a customer for life!
Love this car
This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

Bought 2 cars.
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.

Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.
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

Thank you Delmar for a great experience!!
A huge thank you to our salesman Delmar Fralick! He provided us with seamless car buying experience to help us purchase the CT5 Sport have been eyeing for a while. Communication, the test drive and paperwork all were very smooth. We have bought from Delmar 3 other times at a different dealership and cannot recommend him enough.
I bought this vehicle is a retirement car.
I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

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.

Profesional company, was treated respectfully.
From Alex answering my email promptly to buying the vehicle I was treated with professionalism. I never felt that my opinion as a woman was pushed aside for the opinion of the man I was with. I also didn't feel that I had to roll out my degree to show that I knew something about vehicles.
This was special order veg.
This the next to the AMG model ,what a ride,my other mercede is a E-320 2000 and I still have it for a sedan it’s still in tops condition

Outstanding!
Fine dealership with excellent and professional sales and auxilary staff. My overall joy of pruchase was diminished by a timely bank wire transfer but was in no way shape or form a result of incompetance at MB of Littleton.
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

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.
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.
