I disagree. I put down the deposit because I wanted to reserve my spot in line. Putting down $1k now isn't that much if it might save me $8K in tax credits by having an earlier spot in line.
I still haven't figured out if I can get a charger in my apartment building. I haven't decided I like the look of the car. I haven't even decided I want a sedan.
I love Tesla, so on the chance that I do want the car I put down the deposit. But I'm still 50/50 on actually buying it. I imagine many are in a similar positions.
