- Golden bearSales personnel were very knowledgeable and answered all of our questions that we asked and requested. In the end, they were able to locate the Mazda we requested and they made the financial process pretty simple. Would recommend this dealership to others. This is our second Mazda from them and the staff is the reason we traveled back from Wisconsin to purchase our next one. Keep it up! Thanks,
