Purchased a car via web. Assigned sales associate, Sunni Wang was very professional and responsive and made the transaction enjoyable.
Happy Steve
I used to lease a Mercedes C300, but the Audi A4 has better tech, is easier to use and a comparable ride. I am a happy customer!

My first ever new car shopping experience was flawless.
My first ever new car shopping experience was flawless. Carlos Vargas of Hudson Honda was very instrumental in the process and his professionalism was awesome. I would highly recommend getting your next vehicle from here.
Excellent Vehicle
So happy I extended the lease on my previous A4 to wait for the new 2021 A4s to come in. Except car both inside and out. Meticulous attention to detail and the new standard features in the 2021 A4 are incredible.
