As a woman who honestly knows nothing about cars, I was
As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!
This is a luxury suv with plenty of room.
This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

This is the fourth vehicle that we've purchased from ELCO
This is the fourth vehicle that we've purchased from ELCO Chevrolet, and there is a reason that I returned for my third Tahoe: they're the very best. Three weeks ago, I lost my husband unexpectedly and with two ELCO Chevy's, one 10 yr old Tahoe and a two-year-old Trailblazer that my children didn't want I felt it best to combine the trade-ins and purchase a new Tahoe that will take me another 10 years, providing me not only transportation but the security I need moving forward. The staff at ELCO were respectful, kind, understanding, and efficient. The purchasing experience was excellent from start to finish, and they took every step to make me feel like I was the only person in the dealership those two days. I am very grateful to Mark Gerecke and Branden Nehls for all they did to make the process as easy and comforting as possible given the circumstances. I am an ELCO customer for life.
Updated model
Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Ryan did a GREAT job as did everyone else.
Purchased a 20yr old Nissan from Ryan, he and the team there gave me as much information and the condition of the vehicle as was possible based on the age and of course based on the age the car does have its issues which I had expected, but Ryan did a great job of working things out and as I arrived really late he and the necessary people to finish a deal were there and ready to help. I picked the car up the next morning with a full tank of gas ready for my 300 mile trip home. They gave me a great deal on the vehicle, far below what they were asking all said and done out the door.
