I had an amazing experience working with Dean at Sewell Cadillac. From start to finish, he was professional, patient, and genuinely invested in making sure I drove off in the right vehicle not just making a sale. Dean was extremely knowledgeable, answered every question thoroughly, and made the entire process smooth and stress-free. What really stood out was his honesty and attention to detail. He made sure everything was clear, never rushed me, and treated me with respect the entire time. That level of service is rare and truly appreciated. If you’re looking for someone you can trust who will go above and beyond, ask for Dean. I couldn’t be happier with my experience and my new ride!

Kirsten Osborne is a great salesperson and adds a personal touch. She even added some puppy toys for my new dog with the car sale. Casey Waters is super communicative in the service department when you have an issue Ryan Nemic did a great job at running point from a management perspective when I posted by review regarding challenges with my new vehicle. In short, they do all that they can to improve your experience as a customer when there are red flags. CONS The Otpiq might have some glitches that the manufacturer needs to work on because my car powered down while driving it after only a week and it also required breaks repair. Ask questions! Get proof of the inspections ran on the vehicle, ask for a report with the history of repairs- even if you are told the car is brand new, inspect the car from top to bottom for cleanliness and test drive the actual car and not an example of it before saying yes. I didn't go through these checks and balances and it made for a challenging experience in my first month as an Optiq owner. If your car powers down, pull over as soon as you can and call for roadside service. I attempted to get it home in my parking garage and got stuck at the entrance :/ I attached photos of the notifications should you also experience this and call Sewell right away and they will get a tow truck out.
