Rocco Manganelli
Sales Manager
Cars aren't just my career they're in my DNA. With over 18 years in the automotive industry, I’ve worked hands-on in every single department a dealership has to offer. If it has wheels, an engine, or a set of keys, chances are I've spent plenty of time with it! To sharpen those skills even further, I proudly graduated from the NADA Dealer Academy in 2023. If the Manganelli name sounds familiar, you might remember my dad from his days as a longtime dealer right here on Route 22 before he finally hung up his keys and retired. Automotive roots run deep around here, and carrying that legacy forward is something I take a lot of pride in. Off the Clock When I'm not talking cars or helping clients find their next vehicle, you can find me deep in my favorite role: Dad and Husband. I'm happily married to my wonderful Wife, Jessica, and we've got our hands full in the best way possible with our two incredible kids, John Anthony and Gianna Valencia. Besides being a husband and father my hobby is cars. Whether it’s working on my Trans Am or building my Rock Crawler Jeep I am deeply passionate about anything that has wheels. At the end of the day, I treat everyone who walks through our doors like family. Stop by, say hello, and let's talk cars!
