Probably one of the easiest and most insightful transactions I’ve had. Dave was extremely informative and helped me secure a great loan with an excellent rate. The entire process was smooth, and I was off the lot in no time. My wife and I will absolutely be purchasing her next car through Dave at Big Wave Auto.

Terrific experience and I cannot recommend highly enough. Dave walked me through every part of the process and got a great deal for me on a very niche car. I will definitely be using Big Wave again.

I recently purchased a Rivian R1T from Big Wave Auto, and the experience was top-notch from start to finish. Buying a high-end EV can sometimes be a headache, but these guys made it incredibly straightforward. Very knowledgeable on the topic.

Dave at Big Wave Auto was easily the best sales process I have ever experienced when buying a car. He was extremely adaptable to my situation with being out of state and my timeline for pick-up. He takes great pride in the cars that he sells and made buying a car sight-unseen worry free. Would highly recommend to anyone, no question.

Got this beautiful 2021 Tesla Y from BigWave about a month ago! Dave is very friendly and works hard to find the car you want within your price range. He responded to my texts timely during the entire process. Highly recommend to anyone looking for a pre owned car.
