I accompanied a friend of mine who wanted to buy a car.
He had already researched the car online, had a price quote from dealerships in the area from TrueCar
He was very clear with the trim and the interior and exterior colors he wanted
We drove for over an hour to get to the dealership only for them to waste 3 hours of our time and not have the car in stock on top of the fact that the car would now be $1,000 more.
