Everyone took the time to help me select the perfect SUV
Everyone took the time to help me select the perfect SUV and show me all the features. I have bought from them before. A repeat customer 3 times and I will use them in the future.
Head turner
This car has met every expectation, so fast it is mind blowing. I have put 1000 miles on it in only a week because it is so fun to drive. People stop me to talk about my car.

I was there with a a friend who was getting new tires on his truck and this young man with a backwards pirates hat and glasses on with a mopar shirt was just the most genuine person I have seen made conversation and just all around a great person
Magnaride
Highly recommend Magnaride with Performance Group 1. Lowered the car within Magnaride specs and the car handles so much better. The chassis is rock solid even in convertible style as long as you get the performance pack

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!

Outstanding Experience with Amir at Helfman Ford!
Outstanding Experience with Amir at Helfman Ford! I recently purchased a 2024 Ford Expedition Max from Helfman Ford, and I have to give a huge shoutout to Amir for making the entire process seamless and enjoyable. From the moment I walked in, Amir was professional, knowledgeable, and genuinely invested in helping me find the right vehicle. He took the time to answer every question with clarity, and never once made me feel rushed or pressured. His attention to detail and commitment to customer satisfaction were truly impressive. What really stood out was Amir’s ability to make the experience feel personal. He listened to what I needed, offered thoughtful recommendations, and made sure I was comfortable every step of the way. The Expedition Max is an incredible vehicle, and Amir made sure I drove off the lot feeling confident and excited. If you're in the market for a new Ford, I highly recommend asking for Amir at Helfman Ford. You won’t just get a great car—you’ll get top-tier service from someone who genuinely cares.

Long Wait But Worth It
The appointment for our 2003 Mazda Miata was on 4/6/2022. The wait was especially long; not sure if it was due to overbooking for oil changes or what, but at the end of the day, the best thing about it was working with Richard Smith! He kept us informed of the status of our vehicle because RICHARD SMITH IS "DA BOMB!" 5+ stars!!!

We are very happy with our recent purchase of a used
We are very happy with our recent purchase of a used Outback Limited. Howard Marfell was our salesperson for over two decades. After he moved and left Uftring Subaru we were concerned about having to deal with a new person. Through a referral from a coworker, we went with Travis Doubet. Travis met and exceeded our expectations. It was only 1.5 hrs from test drive to leaving with our next Subaru. He is now our new "Not Howard" :)

Great Service Dept. experience
I had to use this dealership for the first time for some warranty work on my Explorer. The Service Dept. was outstanding. Top notch service and everyone from the phone person that scheduled my appointment, to the lady courtesy driver, were super friendly and very professional. The experience was a very positive one and they will be my new Ford Delarship here in Tulsa, so much better than the one I was using. Thank you Riverside Ford for being an outstanding Service Dept.
