What a fantastic and refreshing way to purchase a vehicle. Dave went out of his way to accommodate the time I needed to look at a car (I traveled 2.5 hours). The pricing was fair and he was upfront and honest about everything. The attention to details was second to none. The dealership is fairly small, but don't let that deter you. There was absolutely NO pressure, as he made sure the vehicle was right for us. I will be calling him again when my daughter and wife need new vehicles.

FANTASTIC!!! Big Wave Auto is a game-changer! Unlike the typical high-pressure dealership experience, this small, customer-focused dealership FOUND exactly what I wanted and was under my budget. Dave was exceptional—personable, professional, and refreshingly honest. It’s clear Big Wave Auto only sells vehicles in pristine condition. This was hands-down the best car-buying experience I’ve ever had and I’m never going back to the old way. Highly recommend!!

Dave does an amazing job. I wanted to buy a Tesla from someone who knows Teslas. I had some pretty specific wants: had to be 2023, had to be white interior, had to have upgraded hardware, etc. Dave found it for me within my price range and rather than driving far, likely out of state, to find this vehicle within my price range, I ended up driving about 6 miles down the road to get it. Any questions or concerns, HMU.

This was by far the easiest most convenient way to purchase a vehicle. Extremely helpful, friendly, and only showed us vehicles we asked about. Never pushy. I highly recommend using Big Wave for your next purchase.

Absolutely incredible experience when purchasing our BMW X7. Very knowledgeable and fair. We will be purchasing all of our vehicles through Dave moving forward. He’s already scouting out another BMW for us. Pretty impressive.

Great service through my first process of purchasing a car. Dave was extremely helpful while my original timeline buying a car went from 4 months to a week… and found my dream car in 5 days!

Five-Star Review for Dave. I recently purchased a used car from Big Wave Auto, and I couldn’t be happier with the experience—thanks to Dave, the amazing salesman who helped me every step of the way. The car had a few imperfections at first, which is to be expected with a used vehicle, but Dave didn’t hesitate to address every single one of my concerns. He went above and beyond to make sure everything was taken care of, and the results blew me away. I honestly didn’t think a used car could come out looking better than brand new, but Dave made it happen. If you're in the market for a vehicle and want someone who genuinely cares about customer satisfaction, go see Dave at Big Wave Auto. Highly recommend!
