Fabulous Experience with Jennifer in the Sales
Fabulous Experience with Jennifer in the Sales Department. She made the process seamless and pain-free.
Very Happy with SL450
Recently traded a 2019 Corvette Z06 for this 2020 SL450. The Mercedes is much quieter and rides better. Quality and fun factor is high. Mercedes infotainment system and menus needs to be more user friendly.

My initial experience is very positive, but I do have
My initial experience is very positive, but I do have reservations about the title work. I’m from out of state and the only form they had me sign was for Washington State. I will fly in to pick up my car and we’ll iron out those details. Great group of people.
Have only had it a day, but it's wonderful.
This is head and shoulders the most comfortable car I've ever driven. Favorite things: * Convertable-ness * Magic sky * Seat bolsters * Massaging seats * The way it feels cornering * The throaty exhaust

Been dealing with Dan for over 10 years, he always looks out for me and hooks me up. Count on him for everything, when I need a car, he helps me with financing, trading in the car I have now, and service at his shop when I need it. I have his phone number saved and can always rely on him.

I did some research before going to UAC and everyone
I did some research before going to UAC and everyone lived up to the reviews that I read. It was great family atmosphere and I felt like I knew them for ages. When I walk in the door with no appointment I was greeted by Baker who was very professional and polite. I informed him about the car that I was interested in and he gave all the details, Carfax information and explained all components from the beginning until I left. Finance went extremely smooth I was in and out. It’s no words that I can explain about Jessica like I said early I felt like I known her for years. She treated me more like friend/family not just like a customer. Jessica was extremely accurate with numbers and we discussed the payment and interest rate that will suit me. She is passionate about doing the best for you. Overall outstanding experience. If you looking for luxury car or truck please check them out. I will return.

All in all this was a very pleasant car buying
All in all this was a very pleasant car buying experience. Tom Dempsey, the owner of the dealership, personally found me the car I was looking for at the price I could afford. Elijah then took over and did an amazing job showing us how to operate all of the electronic features this car has. He was extremely professional and patient and he walked us through everything. I will recommend this dealership to all my friends.
