Love My New Ride
I saw an add for a vehicle through Facebook that took me to their website. I called the dealership to come take a look and test drive. Fell in love and the rest is history.

Update to previous review (Unreal) Not the case
I posted a previous review that I was upset about the brakes on the vehicle I purchased. Posted the review because I didn't believe that they would help a customer out because of the previous reviews I read. This is not the case. After posting my review Alex R (GM) reached out to me and left his phone number so I could contact him. Alex is truly trying to change the perception of the business and is very professional. He sent me a check for the money I put into the vehicle to get the brakes fixed. He did not have to do this but he did. Before you over react as I did and posting a review, I would recommend contacting Alex. He's patient and listens to what you have to say. Never interrupted me one time. The few words he said were "what can I do to make this right." I think GretnaAuto has something good with Alex and I hope the see it themselves as well.

I can't say enough good things about purchasing from
I can't say enough good things about purchasing from Copple. We dealt with Adam and Ethan and no pressure was given. My family has purchased many vehicles from Copple's for a very long time now, and we will continue to work with them. Thanks

Bought a used vehicle from Brant.
Bought a used vehicle from Brant. We discussed pricing the evening before. From the time I entered the dealership until I drove off with my new vehicle was less than 2 hours! Very transparent pricing, with an honest sales person will bring me back again! Could not have been a better experience!!
