Meet Jonathan DeLeon
Go Car Advisor℠ was founded by Jonathan DeLeon, a Massachusetts-based vehicle advisor helping clients make smarter decisions when buying, selling, trading, or financing a car.
Since 2022, Jonathan has been helping friends and family navigate vehicle purchases, sales, trade-ins, dealer conversations, and negotiation decisions. After seeing how much stress, confusion, and money could be saved with the right guidance, Jonathan created Go Car Advisor℠ as a specialized client-first advisory service.
“Dealerships negotiate every day. Most buyers only do this every few years. My job is to help level the playing field and make sure my client understands the deal before signing.”
