I really like the back and forth when purchasing a new vehicle, today for a few bucks you can get a print out that will show the exact price of the make and model you are looking for and what it actually costs for any of the add ons.
The key is to be willing to walk away, which we have done a few times if we cannot make a deal.
The last 3 vehicles we purchased not counting our van, I purchased over the phone or on-line, most people today have nationwide free calling, and it can save a person a lot of money to spend a few hours searching for the vehicle you want, unless it's a specialized vehicle like our handicapped van was. The mark up on those things is crazy, they know you need it, there is not much out there, and they are going to screw you over.
When we purchased the last one a new Toyota Seinna, 2021 already had the ramp installed, we paid right around $71,000, when I sold it back to the same company less than 2 years later, only 18,000 miles on it they gave us $49,000. Which was the highest offer we could get, some wanted to give me around $42,000 to $45,000. They then turn around and want to sell it for $63,000. Nothing but a rip off.
