I was born and raised in Cape Town, South Africa. Immigrated to Vancouver, Canada where I joined the Canadian Army. I met my American Special Forces Husband of 34yrs on the air force base where I was stationed. I then moved to Sacramento and now live in Shingle Springs!! I have been a Talent Scout for 30years but when COVID struck it changed my career direction. I found the Automotive industry very similar to finding talent and placing them on the right path. Meeting customers and getting to know them is my greatest pleasure and my gift of finding them the right car is such a joy. I have always been an advocate for customers and making sure they have the best experience. I pride myself on making sure every customer feels my integrity, honesty and pure joy when we find them the perfect solution to their needs and wants!!

Billy Bonner and Creed Cate were Outstanding! Professional, competent, courteous, knowledgeable. The post-sale add-on visit was less so. The following is my note to Billy Bonner on Apr. 28, Professional, competent, courteous, knowledgeable. The post-sale add-on visit was less so. The following is my note to Billy Bonner on Apr. 28, shortly after that meeting: "I write because, on reading the descriptions of the four package plans I bought at the post-sale, add-on visit, being the “Ultimate Care +, Hydro-Ramic Plan, Paintless Dent and Tire & Wheel, totaling some $4,300, I’ve got these questions: 1) I was told that, “In 2017, BMW stopped doing any maintenance on its vehicles, other than changing the oil.” Ergo, I’d need to spend $1,300 on the ‘Ultimate Care+” plan, to avoid having to pay for any of the routine maintenance items (that I’m obligated to do during the lease). Really? They’ll "only change the oil?" They won’t put in a new oil filter or change the air filter? Or check the fluids in the battery, transmission, universal joint, radiator? ‘Won’t check the tire pressure/look for leaks? Clean any cabin air filter(s)? I’ve driven BMW’s for almost 40 years ('86 635csi, '01 X-5, '22 M850), and they’ve always received this and more maintenance, without extra charge. Having to buy this additional coverage for another $1,300 makes no sense. 2) Diane told me that, to ensure that the exterior paint would remain “nice and shiny,” I’d need to buy the Hydro-Ramic Plan. The “Plan” states damages such as “prematurely fade, oxidize or otherwise reflect a deterioration,” are covered if caused by: “sun exposure, acid rain, bird droppings, tree sap, water spotting, humidity, dirt, weather, detergents, hard water, magnesium, sand abrasion, calcium chloride (except as limited on the reverse side, which sets forth all the exceptions/ exclusions to the coverage). Really?? We live a long way from acid rain, magnesium, calcium chloride or sandstorms, and I garage my car. It seems a stretch to say the factory-applied paint job on the hundred-thousand-dollar+ car won’t remain “shiny” without spending this additional $1,300. Also, as to protecting the car seats against stains from “blood, urine, mold or mildew," the chance of any of those occurring from my use of the car is not high:). Together, the four plans bumped the price of the car by some $4,300 (about 8% or so of my lease cost), for what appears to be only marginal benefit. ‘Would very much appreciate your take on such. ‘Best, Brian More

He was quick to address various issues we raised, showed great patience and follow-up, and worked cooperatively with us to reach a lease agreement. We also appreciated working with Ms. Wallace in the credit department. I asked a lot of questions that required detailed responses, and she handled herself well. We are long-time MB owners. This is our first BMW. Based on how we have been treated so far, it will not likely be our last. More
