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!!

We arrived less than 60 mins before closing on a holiday. We were super impressed and we went home with a new car. It was after closing and more than one person was still there working. You don?t see that these days. Our car salesman even took a selfie with us.

Excellent service from Morgan Smith !!!!
I know how everybody always runs to write a review when it comes to anything going wrong! I think it’s equally as important to let people know when you have excellent service. I bought a 2014 Q 50 from Morgan yesterday and it was absolutely a seamless transaction.... The first time with visit in a dealer that has the hassle free attitude and fortitude, this was the first time that it was actually exercise correctly ! Morgan thank you for the care and time that you put in on my quest !!!! Kindest, AS You rock!66
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.

Clear and timely communication from Delmar.
Delmar was excellent to work with. He was responsive and clearly communicated throughout our car buying experience. I would recommend him to anyone looking to buy a new car.
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.

The Quest
Avery was very good he met me when it was convenient for me he also didn't quit looking when I didn't find quite what I wanted he listened and found exactly what it was that I was looking for the financing which was already pre-approved for me was still helpful from their dealership because they got me an even lower interest rate we would definitely go back to the dealership and in the future would buy another one from them
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

I always buy here.
I've been living in Castle Rock for 11 years now and found Greenwood Automotive about 8 years ago. I typically changes vehicles every 9-16 months for the simple fact, I like new rides. The crew at Greenwood ALWAYS hooks me up. From taking back my last car to putting me into a new one, the process in literally seamless for me. Over the past 8 years I've purchased and traded in a dozen vehicles without regret. This past week a Mercedes E500 caught my eye and within 2 hours I drove it home, seemless. I literally no longer shop anywhere else. Do yourself a favor, call Steve at Greenwood and treat yourself to a new ride.
Muy confiable seguro excelente
Tiene mucho espacio, perfecta para lo que necesitaba, muy cómoda, segura para mi famlia este modelo es un espectáculo, los asientos muy cómoda, buen motor.

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

Terrific Buying Experience
Terrific experience. Team was a pleasure to work with. Adrian was very tentative, professional and helpful I would highly recommend him. Micah was terrific and the process and team were fast and efficient.
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.

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.
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.

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.
