Tiffany at Winchester Mitsubishi is amazing!
Tiffany at Winchester Mitsubishi is amazing! She’s incredibly knowledgeable about the inventory and helped me find exactly what I was looking for without any pressure. She also walked me through the financing process step-by-step and made it feel simple and stress-free. You can tell she really knows her stuff and genuinely wants to help. If you’re looking for someone who will actually listen and guide you through the whole car-buying experience, ask for Tiffany—you won’t regret it!
Overall great car
This car does it all. It’s perfect for the weekend, the daily ,the snow, the rain and it’s pleasure to get in every day. Will probably own this one for the long haul.

Excellent service and profesional salesperson Gloria
Excellent service and profesional salesperson Gloria Vinas is Amazing very knowledgeable and generous person she kept all the best standards in the customer care Thank you to her and Magela in financial department I really appreciate everything things
2018 was a good year!
I have owned two earlier versions of this model and two other models from Audi and I am blown away by this car’s newer levels of luxury, fit, and finish! The newer features and amenities are quite nice too! The virtual cockpit and massaging seats are amazing! I am still learning the vehicle so I’m sure some things are being left out!

Once a car is brought from Carshop the most reliable aspect is service shop they serviced my car with expertise at a critical need . Buy a car from them you’re satisfied. They have great vehicles Penske standard. Carshop Wins . Customer Wins. Peter Alexandratos
Very well rounded daily commuter
Coming from an extensive list of cars owned I can confidently say that my 2018 Audi S4 is the best all around vehicle I have owned. Some might quabble about the plain exterior design but personally find it simple and sleek. Audi has had a long history of interior refinement and it shows immensely with the new S4. I was a little reluctant getting an automatic but I can say once you get behind the wheel of this car in sport & dynamic mode it's absolutley a thrill to drive.

We were interested in a vehicle at CarMax about 275 miles
We were interested in a vehicle at CarMax about 275 miles from where we live. We paid to have the car delivered to the location near us. There was nothing specific that the CarMax dealer did other than be sure the car was moved as quickly as possible. We did not visit the location where the car was being offered and the car was not delivered to our home.

Amazing customer service in service department
Bought my vehicle from Golden, CO Carmax and didn't have any support for mechanical issues. Still purchased the vehicle because it is what I wanted. Ashley from sales in Golden was the worst! I ended up closing the deal with Cora who was amazing and clearly the exception to the rule in Golden. When I told Ashley there were issues with the brakes she was rude and didn't take me seriously. I ended up working with the Federal Heights dealership on repairs. Debbie in the service department took this on and was soooo amazing! She took care of everything and I am so greatful! The technican at this location was amazing as well (I forget his name unfortunately)! It is really a shame that I had to go to another location to get service, but I am so glad that I did. Outstanding job Federal Heights location!

I saw the car on the website, we went to the dealership and Abraheem and his team let me see the inside of the car, drive it and my family and I loved it. Abraheem offered us a good price and in less than 3 hours he helped us with a loan and we took the car. I will buy more cars with Main Street Motor again. 100% recommended.
