This place was an 11 out of 10! We have been test-driving Jeeps for years, and the perfect one finally showed up on this lot. We received a warm welcome as soon as we arrived, and they answered all of our questions. Working with Ignacio “Nacho” Gonzalez was fun and easy. We test-drove the Jeep twice, made an offer, and drove away in less than an hour! Their finance guy also worked out the most AMAZING deal for us. I am so thankful for their help in making my dream car a reality. I cannot recommend them enough!... More

Ignacio “Nacho” Gonzalez was so helpful, kind, thoughtful, and professional in helping my wife and I find the perfect vehicle for our family. Our experience with him was wonderful. I recommend you go and talk to him about a vehicle that will work for you and your family today!

I had a fantastic experience working with Ignacio “Nacho” Gonzalez! From the moment I walked in, Nacho was incredibly helpful, friendly, and professional. He made what can often be a stressful process feel easy and smooth. He answered all my questions with patience, guided me through every step, and truly went above and beyond to make sure I was comfortable with my decision. I couldn’t be happier with the service I received—if you’re looking for someone who genuinely cares and will make your car-buying experience a breeze, ask for Nacho!... More

I had a wonderful experience here. I came in to look, wasn’t expecting to buy anything due to some unfortunate circumstances. But when I saw that they were able to help me with certain things I couldn’t pass up the offer. I am so thankful and grateful for Mike P. He was so helpful and answered all of my questions about purchasing. I left with a new vehicle with a great price and payments. Thank you St. George Auto!

Our online price is our no-haggle, upfront price and already includes all available discounts, including our dealer-arranged financing incentive.
This price can’t be combined with any other specials or promotions.

Paying cash or using your own outside financing removes the dealer-finance incentive, which means the final price will be higher than the listed internet price.

Tax, title, license, and dealer fees are not included in our pricing.

Offers seen on TV, radio, mailers, social media, or print ads are separate and cannot be combined with our internet pricing.

We make every effort to list accurate vehicle information. Options and features come from third-party sources and, while usually reliable, are not guaranteed.
Please call or email us to confirm options, pricing, and availability.
