Do I need an appointment to visit a car dealership?

You don't usually need one, but an appointment helps. It ensures the specific vehicle you want is on the lot, cleaned, and ready to drive, and that someone is available to help you. Confirm by phone or email that the car is still available, ask for the VIN and an out-the-door price quote in writing, and note who you spoke with. Weekday mornings are often quieter than weekends.
