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!

This dealership's integrity is what sold me my new car. I've been researching new cars for weeks. Over the weekend, I visited several dealerships. One of them being Hardy Chevrolet. After being hassled around, pressured and lied to by other dealerships, I returned to Hardy Chevrolet on Monday because they were the only ones who were upfront and honest from the beginning. I'm a proud new Chevy owner and so grateful to Hardy Chevrolet for making this a pleasant experience! Ask for Paco!!
Nice for what it is
Meets my needs. Plenty of power. Lots of room. Hauls and tows like a dream. Very nice and stylish truck considering that it is a W/T.

Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

All I can say is GREAT things for this company and Andy
All I can say is GREAT things for this company and Andy Rosales as a salesman. I came here looking for a low mileage nice Golf. I didn’t have an appointment but Andy Rosales came out right away and came across as an acquaintance/friend rather than a salesman right off the bat, and didn’t try to push a sale on me at all. Just asked if I wanted to look and test drive some. I test drove 4 cars, and Andy was super nice about letting me test drive all the vehicles I wanted to look at. they had 3 options on site and another at another location here in the springs. I just came to test drive the first day and was planning on going home and sleeping on it. And they had no problem with that and just provided a phone number to reach out. No pushy salesman tactics you see at most auto dealers, by the salesman, manager, or financing manager. I came back the next morning to talk numbers. I did my research on the vehicle and they were very transparent with me throughout the whole process. Like any dealership, negotiation skills are helpful, but I truly believe based off my experience that this dealership is truly not out to scam you. I got the EXACT car I wanted, for a veryyy competitive price. I am 100% coming back here as far as I’m concerned.
Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

Love my new Explorer
Came here for a really great looking Ford Explorer, the salesman Will was great and had paperwork for the recent suspension components the dealership replaced after finding some issue during their safety inspection. Ended up going home with the rig. I absolutely love it!
