First experience working with Big Star Chrysler we’ve always gone through Big Star Honda. From the moment we entered it was like we found our second home dealership wise! Manny was our salesman and went above and beyond to take care of us. Though it was a used car Manny made sure this vehicle was worked on and like brand new before we drove off with our Sequoia. Big thank you to Manny! I wouldn’t trust anyone else!

We recently bought our second Toyota from Don McGill.
We recently bought our second Toyota from Don McGill. The first was a 2020Toyota Avalon and the second was a 2024 Toyota Crown. The first purchase went off without a hitch and we were very satisfied. The second car (the 2024 Crown) was purchased and delivered on 12/29/2023 with only one key FOB; I was told me I would get a second key FOB in six months. I subsequently talked to the service department; they promptly ordered one and I received it one week later. I do have an issue with the title department. My credit union is threatening to raise my loan interest rate if they don't receive the title. The only way to satisfy my credit union is to explain the process which I do not understand. The dealer should be more proactive in ensuring that the sales process does not end with delivery. My credit union still hasn't received the title. I am forced to keep calling which shouldn't be necessary.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

I cannot recommend this location enough after the excellent service and very good experience I had with my first time financing a vehicle. Cesar Rodriguez and Raul Silva both worked with me to find a vehicle that suited my needs within my price range. These gentleman were extremely patient and professional when handling the sale. I would also like to thank Mark and Brandon in financial services. They both persisted through technical difficulties in order to deliver excellent customer service all the way to the end. I would absolutely recommend this location if you’re in the market for a used vehicle and I will be returning in the future!

Very professional, great group.
Very professional, great group. Last Tesla I bought was purchased from a group that sells 50-65 teslas a month (idrive in Carrolton tx). Auto Boutique surprised me, and managed a Tesla sale like a group that sells 10x more of these technically challenging vehicles. They got the car added to my Tesla app quickly and I left the dealership able to supercharge and drive 6 hours to my home. The young guys ( Ethen Beck and Enrique Ovalles) were very Tesla literate. I'm a contributor to a tesla owners forum and have over 4 million content views, so I'm not a Tesla Newbie. I have a 2016 model s p85, a 2021 model y dual motor, and now a 2021 refresh model s long range to replace the aging ap1 car. These guys had the recurrent battery report in addition to the carfax so I could skip checking the battery. Staff went into service mode and we checked the error log. They got an update to post before adding the car and so I drove off in great shape!

I recently had an exceptional car shopping experience at Auto Boutique. From the moment I walked through the door, the staff was incredibly responsive, addressing all my queries with patience and professionalism. They were genuinely helpful, guiding me through the process without any pressure, ensuring I felt informed about my choices. The politeness of everyone at Auto Boutique was particularly noteworthy; they made me feel valued and respected throughout my visit. I have not yet found a car that perfectly matched my needs but left with a positive impression of what customer service should be. Highly recommended for anyone looking for a smooth and pleasant car buying journey.
