Put it on your own terms. Every time I've purchased a car for the last 15ish years, I decided on the model, specs, and price I want to pay. I then searched inventory at every dealer within 2 hours of driving and emailed their internet sales manager an offer. I take the lowest two, try to negotiate a few more times via email, sending the lowest quote to the next lowest, etc... once I'm happy with the price, I ask for an out the door itemized price, agree on it, and agree on a meeting time. I show up, sign some papers, drive away.

How is Tesla's process much easier than that?
