On my last purchase, I did my homework online and find the dealer's cost of a vehicle. With that in mind, I walked into a dealership, waited 3/4 hour for a sales tech, and said, I have X amount of money in hand. I want to walk out with the said vehicle. 9 out of 10 times they will say it can't be done. After talking to the sales manager and others, sometimes they will negotiate. You may not get what you want in terms of color, or accessories, but you will get a set of keys. They know you will go elsewhere!
Since I negotiated for a basic model without accessories, I ended up with an upgrade with accessories on the lot for the same price as the basic model! You can search dealers' inventory for a similar vehicle in your mind and go get that vehicle! Sometimes they will ship a vehicle from another dealer.
Just do your homework and play the waiting game in the showroom. Time well spent!
