1717 Gravesend Neck Road,
About Us
Brooklyn's European Auto Repair Authority Since 1985
When Jordan Weine opened Bay Diagnostic on Gravesend Neck Road in 1985, the pitch was simple: dealer-quality service, without the dealer runaround. Forty years later, we remain a family-owned Brooklyn institution where the owner is in the shop every day, ensuring your vehicle receives the precision care it deserves.

Our Story: A Vision for a Better Shop
Jordan Weine has been in the automotive industry for over 51 years. He started Bay Diagnostic in 1985 because he saw a better way to do things, and he wasn’t interested in running the kind of shop that made customers feel like they were being processed, not helped.
That philosophy is still the operating principle. Bay Diagnostic isn’t a franchise. It doesn’t have investors to answer to. It has one owner, and he shows up every day. Jordan is at 1717 Gravesend Neck Road, Monday through Friday, 7:30 AM to 4:30 PM. If you have a question, you can ask the person whose name is on the building.
Beyond the shop, Jordan has spent decades raising the bar for the entire industry. He served as chairman of the Gasoline and Service Station Dealers Association, a group dedicated to elevating professionalism among independent auto repair owners. He also regularly contributed expert insight on The Auto Lab, the longest-running live automotive talk-radio show in history. The depth of knowledge that Bay Diagnostic brings to your car isn’t accidental; it’s been built deliberately over half a century.
Why Drivers Across the Five Boroughs
Choose Bay Diagnostic
There’s no shortage of repair shops in Brooklyn. The question is which one actually knows your car and gives you a straight answer. Here’s what separates Bay Diagnostic:
The owner is always available
Not a manager. Not a service writer. Jordan Weine is physically present and reachable every business day. That level of access doesn’t exist at a dealership.
Honest recommendations — nothing more
You will never be sold a service you don’t need. Bay Diagnostic’s reputation is built on 40+ years of that policy, and over 2,000 active customers who keep coming back because of it.
Ratings that outperform the dealers
Check the reviews. On average, Bay Diagnostic carries higher ratings than the local dealers. The results are public — no claims necessary.
Your manufacturer's warranty stays intact
Bay Diagnostic adheres to all factory-maintenance intervals and uses OEM parts. Servicing here will not void your warranty.
APPROXIMATELY 35% BELOW DEALERSHIP PRICING.
Dealer-level work, independent shop pricing. The equipment is the same. The overhead isn’t.
Don’t just take our word for it — read what Bay Diagnostic customers have to say.
New: A Dedicated Mercedes-Benz Specialist on Staff
Mercedes-Benz owners in the Five Boroughs now have an option that didn’t exist before. Bay Diagnostic has added Dennis to the team — a senior Mercedes-Benz technician who came directly from a local MB dealership with 25 years of exclusive Mercedes experience.
Dennis services the full Mercedes-Benz lineup, including Maybach and mild-hybrid models, using factory diagnostic tools and procedures. For owners of AMG, S-Class, G-Class, GLE, and the rest of the Mercedes range, this is dealership-level expertise at a fraction of the cost — and with Bay Diagnostic’s commitment to honest, no-pressure service behind it.
No independent European shop in the Five Boroughs can match that depth of Mercedes-specific experience. Learn more about Bay Diagnostic’s Mercedes-Benz repair services.
