A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

This is a great dealership to do business with. Very down home! I have purchased 3 vehicles in 3 months. Seguin Chevy was by far the best dealership I worked with. I highly recommend them if you are in the market! Sam is a great saleslady!

Positives: 1.
Positives: 1. They offered me a fair value for my trade in. 2. They were willing to match the best deal I had found on a similarly equipped vehicle in the area. 3. Everyone at the dealership is very nice. Negatives: 1. One caution I'll share has to do with the finance/business manager experience. He's very charismatic, very charming, a good salesman some might say. He will attempt to sell you on the usual extra services and coverage. Then he'll go through a presentation on the manufacturers warranty compared to a 3rd party warranty. That little presentation includes some inaccuracies. He either hasn't read the contract or lacks proper understanding of how it works. He will then reassure you, that you can get a full refund within 30 days after you've had time to read the contract and lookup reviews. However, this is only partially true. In the state of Iowa extended warranties are taxable contracts. When they show you the price, it doesn't include the sales tax. That will only be shown once you've agreed to the price and go through the signing process. (red flag #1) Please Note: you will not have internet service inside his office and their public wifi does not work. If you attempt to cancel the contract that they sell as fully refundable within the first 30 days, prorated after that, you will find out that they will refuse to refund the tax they collected (even if it's just 1 business day after your purchase) and claim once it's sent to the state they don't get it back and won't be able to refund it to you. This is what some might call a lie by omission. (red flag #2). By the way, they don't sell the GM Extended warranty (likely because they don't make as much money on it), but if you're interested in it, it's significantly cheaper and you can get it for 12 months longer and 10k mile more coverage than the 3rd party warranty they offer. (red flag #3) All in all, I'm happy with my purchasing experience and would buy from them again. I'll just be on guard a little more when it comes to meeting with the business/finance manager. I know they have to make their money to, I just don't like being lied to. Even if it was just an error I think they should have made it right which they did not do. I hope this review helps someone be a little better prepared than I was.

We had a wonderful experience at Unique Auto Group. We found the vehicle online and called to say we were interested. They had the vehicle pulled out and ready. The price was excellent and as advertised. No hidden fees or problems. Amir was great! He helped through the sales process, and everything went without issues. I highly recommend buying a vehicle from Unique Auto Group! We will definitely buy from them again!

Just wanted to say thanks again to Kevin Olmstead for all of his help and effort in getting me into my new vehicle. Kevin continuously kept in contact with me with any questions I had or information I was seeking out and also handling the communication well after business hours. A fabulous and dedicated specialist and my first experience with him. I'm also a Feldman CDJR customer as long as Kevin is there. Terrific job again Kevin. Thanks Feldman CDJR.

I am absolutely THRILLED with my experience dealing with
I am absolutely THRILLED with my experience dealing with ✨ANDREA✨ at Wyatt Johnson Toyota! I recently sold my beloved Camaro in order to buy a 2023 4Runner TRD Off-Road Premium, and I couldn’t be happier. Andrea, our saleswoman, was simply amazing. She was so down to earth and ✨easy✨ to talk to! I genuinely looked forward to every visit. Andrea made the entire process feel effortless and, honestly, SO fun. 🤗🤗 Just like most people, I usually despise the car-buying process, but this experience was COMPLETELY different. Andrea made it incredibly enjoyable from start to finish. The 4Runner is pristine, and Andrea went above and beyond: she made sure the gas tank was FULL when we drove it off the lot. Small talk and kind gestures speak volumes to me. When you decide you want to go to Wyatt Johnson, don’t be silly and let the front desk choose a salesperson for you! Ask for Andrea!!! You will literally want to hang out with her after! You will have to have a mini mirror session where you look yourself directly in the eyes and talk yourself out of texting her to ask if you can go to her Halloween party 🤣. That’s how I know I was treated right, not tricked (see what I did there🫣😂) Wyatt Johnson management if you are reading this, give that girl a raise!!! She DESERVES it!!! She is really doing the most, in the best way possible! P.S. I do not know Andrea personally, and no one has bribed me to write this review, I’m just expressing my genuine satisfaction with the service I received! Thank you Andrea!! 🩷🩷 Syanne
