FAQs
Yes. We'll bring the car to you, or arrange a test drive at a dealer near you. No obligation. No pressure.
Yes. Vantage is a licensed auto brokerage. Your manufacturer warranty is fully protected—same as buying from a dealer.
Dealers mark up cars by $2,000-$5,000. We're brokers who get you wholesale prices. Dealers pay us (not you), so we can offer zero buyer fees.
We'll get you competing offers from our 350+ dealer network. You pick the highest offer. Better than Carvana's lowball.
Yes. Free delivery anywhere in the USA. We bring the car to your driveway, ready to drive.
There isn't one. This is how car buying works in Europe—brokers handle everything. 96.5% of our customers refer friends and family. If there was a catch, they wouldn't.
An auto broker is your insider at hundreds of dealerships. Unlike traditional car dealerships that work for themselves, auto brokers work for you; negotiating wholesale prices that aren't available to the public.
At Vantage Auto Group, we shop 350+ dealers across New Jersey, New York, and Connecticut to find you the best deal on any new vehicle. We handle all the negotiation, paperwork, and delivery, so you never have to step foot in a dealership.
The result? Our customers save an average of $2,000+ compared to buying directly from dealers, with zero hassle.
Like a buyer's agent in real estate. The seller pays the commission, but the agent works for you. Car manufacturers and dealers pay us a fixed-fee to find qualified buyers, not a percentage of the sale price so incentives are not misaligned.
You pay zero broker fees. We get you wholesale pricing because we eliminate their showroom overhead.
