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.

It was very welcoming and no pushy sales. The sales man was knowledgeable about the vehicle as well as the process of purchasing, and all the way up to insurance and registration requirements.
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!

Rob is your go-to Ford guy!
Rob has helped us with two cars this year. He listens to the customer and their needs. When you visit this dealership, ask for Rob! Nick, from the finance department, helped us this time. He was awesome too! However, I can?t say to ask for Nick because both of their finance people at this location are amazing. Prepared, quick working, and doesn?t dwell on paperwork or trying to sell more. Long story short, you?re in good hands.

The names from used cars: Dax, Ronald, and Mr.
The names from used cars: Dax, Ronald, and Mr. Lee! I don't have perfect credit, alot of money, or time but they made the experience great. Dax and Ronald got me a great car and Mr. Lee got my down payment and monthly payment lower than what I expected. They have patience and treat you like you're a plus customer. My 4th car from there. Always get treated like royalty. Remember I'm not wealthy. Best used sales team ever!!

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
