Owner / Service Advisor

Lewis A Defeo

Lewis is the founder and vision behind Ultimate Bimmercare & Performance, but his journey into the BMW world wasn’t through a toolbox. While he doesn’t work on customer cars directly, his technical knowledge and lifelong passion for performance vehicles are the backbone of everything the shop stands for. That passion started at the age of 8 in Puerto Rico, where Lewis was captivated by his dad’s best friend’s MK4 Supra, one of the first single-turbo conversions on the island. As he grew, so did his captivation with cars, and most weekends were spent playing Gran Turismo and flipping through tuner magazines with his cousin. The import scene drew him in with its creativity and spirit, but it was a rare silver E36 M3 with Vader seats and Motorsport wheels that quietly planted the BMW seed. Over the years, he became more and more fascinated with the brand, eventually owning several models before landing the one he truly wanted: a V8-powered E90 M3 with the legendary S65 engine. To Lewis, it’s peak BMW, a future classic and the brand's boldest expression of modern engineering. Despite working in a different industry, a chance opportunity led Lewis to a new path. He was offered a job as a service writer at an independent BMW specialist, not because of prior experience, but because of his genuine knowledge and enthusiasm for the brand. It started as a leap of faith, but he jumped in headfirst, excited to finally be surrounded by the cars he loved. The result? He excelled. The role came naturally, and for seven years, he thrived learning the ropes, building relationships, and developing a deep appreciation for the service side of the industry. It didn’t just light a fire, it sparked the ultimate dream: to create a BMW specialty shop of his own. Today, that dream is a reality. Lewis leads Ultimate Bimmercare with the same energy and obsession that brought him here, offering BMW and MINI owners dealership-level service powered by enthusiast-driven care.
