Three words describe BMW North Scottsdale and my Pre-Owned Sales Advisor John Sarno, professional, knowledgeable and friendly.
I'd been shopping around for a new (used) X5 for about 2 or 3 months and never purchased a BMW in the Arizona market. I visited Chapman, but was disappointed with their selection and the helpfulness of their staff so I headed up north to BMW North Scottsdale. Wow, what a difference. Their used car selection is indoors so don't have to sweat in the Arizona heat and their sales staff was super-friendly. In addition, this is a no hassle sales environment. If you want help, go ask them as they don't want you to feel like they are a hawk looking for its prey.
My advice, ask for John Sarno. He is a super nice and helpful guy who makes the sales process easy.
