Had a great experience with the service advisor, Eric on
Had a great experience with the service advisor, Eric on 8-27-25. Had a some questions for an app't the following day. Arrived at 5:00 and not only did Eric, the service advisor, save me a couple of hundred dollars, but was able to get the recommended service completed in a half hour without having an app't. I have not always had great experiences but this made up for the lack of attentiveness in the past. Have been a customer since 1990 and will continue to have Planet Honda in Golden to service my 2018 CRV Honda.
I had my 2020 Terrain for 5 years before I had any major
I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Very good experience with O’meara VW buying a nice used
Very good experience with O’meara VW buying a nice used Jetta. Quick fast deal without the usual back and forth time consuming runaround. Friendly courtesy call a couple days after to check on us. Thanks Karson, Elva and sales manager Steve. 👍👍
Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

Carlos at Super Auto was professional, patient, and easy
Carlos at Super Auto was professional, patient, and easy to work with. He addressed my concerns and showed me several cars without being pushy. I appreciated his approach.
I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

I cannot begin to express how GREAT they made the car
I cannot begin to express how GREAT they made the car buying experience for me. Canaan was an absolute pleasure to work with, easy going, straightforward, and kind. We also worked with Jason in finance, and he too was fun to work with and made the experience light-hearted and enjoyable. We found a small cosmetic issue with the car when we got it back home, and they were quick to fix it for us (free of charge), all while lending me a Porsche to drive around town while they handled it (which was fun!)... They just made the whole situation easy for us and made sure we felt taken care of, which was really cool to experience. When making a big purchase, you want to feel heard and supported and these guys did just that for us. The dealership is clean, friendly, honest, and professional. You will not regret working with them!
