Hey!
Hey! So I just wanted to say something. This is what I sent Danielle from Schomp Subaru yesterday after I got into my new car and a lease for the first time please read 💕 You are an amazing human, you treated me like I was human. You got stung by a wasp!! And you kept your cool. You didn't stop trying to help me, a stranger that made bad financial decision. Your health took a back seat today after that sting. I am so glad you didn't have an allergic reaction ❤️ Not to mention when I first came in contact with you, you never stopped asking questions on how to get me out of my high car payment and make sure I could go into my deployment knowing I could afford my payment. I was no easy case, negative equity, my new home had me maxed out financially. A 2021 BMW m340i to a Subaru Crosstrek Sport was not a downgrade it was the opportunity to start over, pay down debt, and knowing that my paycheck wasn't relied upon a second job. And what I found particularly amazing was your love for the Schomp philosophy, we are family, and you sharing a story of how you worked for a short time at a dealership that was only about numbers. Your consideration, and love for your job, and love for everyone that comes to you is why I will never buy a car from anyone else but the Schomp family and absolutely from the day now till I die, you will be the only one I talk to and buy from! Please please see Danielle for all your Schomp Subaru needs!! She is absolutely amazing, caring and the best part of all you just might want to have a hug at the end she loves hugs! Thank you Danielle for everything!

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Excellent customer service Mr, Bill is excellent I would recommend friends to him for car services always very professional he communicates easily I have never had issues.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Awesome experience. The five star rating is too low, I'd give them a 15 star. No high pressure sales. Everyone was so nice and helpful, treated us like royalty. Roberto listened to what we wanted to look at, he went through the inventory, and we found the one we loved.

Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Thanks for your service James Hooker. Nice conversation about the sport of Parkour. I've never heard about that before. One word, two words, 25 words.
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Exceeded Expectations
I had a fabulous experience at Schomp Mazda on Havana in CO. Joe Aya was very patient and knowledgeable. I was able to get the new cx50 which is hard to come by right now and I absolutely love it! They made me feel comfortable in the buying process, no pressure and no hidden fees. They exceeded my expectations for sure! Thank you Schomp and Joe!
Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

A+ Service from the car salesman
The experience with the car salesman, Julio, was amazing. Julio took care of me and dedicated his time to helping me get the truck I wanted. I appreciate everything Julio did for me, and I recommend that other people speak with him about buying from the dealer. I also do not find it fair that car salesmen are judged entirely for other departments' mistakes, especially those that car salesmen have no control over. I would not judge a waiter for bad food; therefore, a scorecard should not judge a car salesman for finance mistakes. As a learned lesson, include your salesmen in your deal and go over the paperwork after you are done with these other areas they take you on the dealer. Their report card from the survey directly impacts the salesmen, and even if you get a bad experience in finance, they will blame it on the salesmen. Thanks for your help, Julio!
Awesome trucks
I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.
