Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

The salesman, Jason, was courteous, knowledgeable and low
The salesman, Jason, was courteous, knowledgeable and low pressure. We literally bought the car (2014 Mazda 3 I Sport) in only a little over an hour, including the test drive. No high pressure tactics nor “upselling”. I highly recommend Cransh as well as Jason B.

Great experience!
This was the most welcoming purchase I have experienced. Alex B. is a top notch sale agent that paired me with a beautiful 2024 Corvette convertible. Based on my experience, I will always look to Jupiter for future purchases.

Easy, Efficient, and Friendly Place
I purchase a used vehicle from Post, and was blown away! After shopping around for quite some time, I arrived at Post and loved everything about it. The process was simple and smooth, and we were able to agree on a price before I even arrived. I would highly recommend Post if you're looking to purchase from a small dealer, that very much embodies the people of Texas!

Car buying isn't fun... until it is !!
I do not like car buying what so ever! That all changed as of 72hrs. ago. Let me just say that Hunter and Nick were awesome from start to finish. They made the process simple. Hunter took me on a test drive and had my paperwork ready to go! Zach in Finance took 15 minutes?! 15 MINUTES!! When is the last time that has happened for anyone? Hunter ended up leaving early but Nick stepped in as if he was there the whole time! I can not thank the two of them and the Five Star family enough! Wow! This place is called Five Star for a reason and they proved it! Thank you Hunter, Nick and Zach for making the process stress-free and thank you Kameron for the awesome deal on my new Malibu!

Best Car Buying Experience Ever!!
Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.

No pressure No games Easy buy of a cash car.
I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.
