We were in the market for a car and came across what
We were in the market for a car and came across what looked like a great deal at Walt Sweeney Ford on cars.com. I called the dealership and was put in touch with Brett Jostworth. We made arrangements to come in on Saturday. Took the car for a drive, made a minor request on the interior and bought the car the next day. The reason we made the decision so quickly was Brett. His approach to sales and general nature really made a stressful time not stressful at all. I can’t say enough great things about Brett!
Exceptional!
The ‘21 A4 Premium Plus S Line is my third consecutive Audi ... love it! Quiet, powerful, safe and fast! This conveyance offers a great deal of wonderful, useful tech, too. It’s two tone interior is gorgeous. Love it!

Recomendable 100%.
Recomendable 100%. Excelente servicio, profesional y muy buen trato por parte de Yuniel, empleado de Honda Brickell, es la tercera ocasión que trato con él. También me ayudo en la coordinación para la recogida y entrega desde mi centro laboral para el cambio de aceite incluido el fregado. Pregunta por Yuniel, ¡es el mejor! Es increíble y hace que el proceso sea realmente sencillo. Él va más allá por sus clientes y trata de ayudar tanto como sea posible. Gran servicio y saben lo que hacen. Llevo 15 años con Brickell Honda y siempre lo recomiendo a familiares y amigos.
Happy Steve
I used to lease a Mercedes C300, but the Audi A4 has better tech, is easier to use and a comparable ride. I am a happy customer!

Excellent Vehicle
So happy I extended the lease on my previous A4 to wait for the new 2021 A4s to come in. Except car both inside and out. Meticulous attention to detail and the new standard features in the 2021 A4 are incredible.

Just Trucks
My old car broke down and towed it to Just Trucks for repairs. Bottom line is I ended driving my new car out of the lot just after a few days thanks to Charlie Rice. Just trucks arranged to pay off my old car loan and found a place to finance my new car. Staff at Just Trucks will treat you like family and take care of your needs. Thanks

Caden is a great person to work with.
Caden is a great person to work with. Everything went smoothly, although I am awaiting the shipment of the car to Texas. One of the best things was the thoroughness of detail on the website. Comprehensive photos, video, write up and Carfax. I got what I needed from those descriptions and conversations with Caden.

I cannot retract my previous review but the service
I cannot retract my previous review but the service manager at Rich Morton Mazda is phenomenal and does everything he possibly can to mitigate my recent situation/car issues. He has worked on my vehicle himself and working with me to make sure we come to some sort of resolution. I truly appreciate how customer forward he is.
