You can avoid long waits at the dealership by getting price quotes on your preferred model via phone or Internet. Most honest car salesmen will be happy to remotely negotiate a price with you.
"If the salesman says 'Just come in and we'll talk about it,' that's a red flag," Montoya says. "You want to avoid falling into that."
Be sure to get a written quote you can bring to the dealership when you go in to close the sale and pick up your car. If the price suddenly changes, go elsewhere.
