I bought my last car by calling the various dealerships and asking to speak to the fleet manager. I had the exact model, options and color all decided beforehand. Then you just take the cheapest deal.

If you go in and talk to a salesman, there's another mouth you have to feed. Don't talk to them when you go to sign the deal with the fleet manager either.

And if you need to take a test drive after you've narrowed your choices down, don't go to the dealer for a test drive. Just rent the car and take your time. Just google "rent a toyota" or "rent a tesla" to find out how.
