I give this dealership location high marks for friendliness and professionalism. However, the business model for EchoPark does not appear to be a company that is interested in "earning" your business. Instead, they are interested in turning vehicles and generating revenue at the inconvenience of the customer.
In my instance, I called ahead to make an appointment to view and test drive a vehicle. Arrived on time and checked in. They knew the vehicle I was interested in purchasing because the salesman immediately told me the car had been sold. I explained that an appointment was made and the salesman said vehicles are first come first serve. They cannot hold a vehicle because many people don't show up. I told them that according to my phone call, it was confirmed that the vehicle was still available and they knew that I would be driving 1 hour to view the vehicle and that I would be securing financing for the vehicle.
As a courtesy, they did fill my tank with gas before sending me on my way, but never offered to show me an alternate vehicle or take down my info to keep a lookout for something similar. i.e. it isn't their business model
I'm not sure the purpose of the appointment because it doesn't appear to guarantee anything.
My suggestion is to go and kick tires, but don't mess with the appointment thing because it is a waste of time. If you find something, it is probably a good deal, but be careful, because they might sell it from under your nose.
