I was in for the annual checkup and my salesman Brad
I was in for the annual checkup and my salesman Brad Biondo had reached out to me via email with an assessment of my 2020 car. So I stopped by. Ha- now driving a 2026. That wasn’t the plan. I continue to be impressed with the upgrade. Huge difference in performance and attributes. Brad made it all to easy. Super knowledgeable, reliable, with integrity- highly valued.

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!

It may be pure coincidence, but we took the car in for service: oil change, tire alignment, plus a special item regarding the front passenger door, and it came back with a dead battery. We literally brought it home, parked it for the night, and it was dead in the morning...

Our sales rep, Beau, was fantastic to work with and was very transparent in walking us through the entire process. He agreed to work around our schedule and come in an hour early on New Years Eve to get a deal done. Super pleased with the ease of negotiation and backend paperwork. Win-win for us and the dealership.
