If they work on making the financing experience a bit
If they work on making the financing experience a bit more positive and customer focused, this dealership would easily earn five stars. Overall, I had a good experience at Beck & Masten South. The sales team was helpful, and the process of finding the right vehicle went smoothly. However, the financing department could improve on customer service. It felt like they weren?t as friendly or welcoming as the rest of the staff, which made that part of the process less pleasant.
