About Big Wave Auto in Sussex, WI
Who We Are – Big Wave Auto
Big Wave Auto isn’t your typical dealership. We’re a licensed, bonded, and insured auto dealer based in Sussex, WI, with one clear mission: make car buying transparent, approachable, and enjoyable.
Instead of being limited to local inventory, we give you access to dealer-only auctions and nationwide networks—so you can get the exact car you want, safely and securely. Whether it’s purchased directly from a dealer or sourced through our nationwide auction connections, we’ll handle the details, process all registration paperwork, and even ship the vehicle straight to your door.
By keeping our overhead low and eliminating the unnecessary extras of traditional dealerships, we pass the savings directly on to you.
Big Wave Top 3 Principles
Transparent, Trustworthy, and Secure
We only buy cars we would purchase for ourselves. That means no dealer fees, no gimmicks, and no games. If something isn’t right, we make it right—because at Big Wave Auto, we follow the Golden Rule.
Approachable & Affordable
By cutting out unnecessary markups and focusing only on the essentials of a car transaction, we make high-quality vehicles more affordable. You get the same access to nationwide inventory as big dealerships—without paying for their overhead.
Fun & Exciting
Buying a car should feel like a treasure hunt, not a chore. With Big Wave Auto, you’re not stuck with what’s sitting on a local lot. Instead, you get exactly what you want while enjoying a stress-free, personalized experience.
A Lifelong Passion
Big Wave Auto was born out of a love for cars and a frustration with how the used car industry operates. For years, I watched friends and family waste hours at dealerships, pressured into unnecessary add-ons, and stuck with hidden fees. After more than 14 years of experience and 25+ personal car purchases across the U.S. and Canada, I decided there had to be a better way.
That’s why I created Big Wave Auto: a customer-first buying experience that cuts out the middlemen, connects you directly to the best inventory, and delivers transparent pricing every time.
This isn’t just business—it’s a team approach to car buying where everyone wins.
Thank you for considering Big Wave Auto for your next vehicle purchase. I look forward to helping you find the perfect car at the right price.
