Thank you for visiting the DeVoe Cadillac web site. The DeVoe Automotive Group has been doing business in Naples since 1968, earning an unparalleled reputation for customer service. We’ve worked very hard to earn that reputation by treating our clients with the utmost respect.

I’d like to personally invite you to the dealership to experience it first hand. Our Sales staff has an average employment length of 12 years, which allows us to develop a loyal and long-lasting relationship with each of our customers. DeVoe Cadillac is setting the standard for customer care. We pride ourselves on the fact that we are nationally ranked for customer service and sales. We were the #1 Certified Pre-Owned Cadillac dealer in the country for 2009 and look to continue that tradition for 2010. Our Sales department for new cars has been a top 10 dealer in the nation consistently as well.
