This type of comment always confuses me. Yes, tax incentives are paid for by everyone in one way or another but I've never heard of a rich guy not taking tax credits because he was worried that these weren't truly "free" money.
Also, I didn't see anything about his ability/inability to afford the car. I regularly wait for Black Friday, etc. to buy things I can afford because I'd rather get it discounted than pay full price.
@rorystewart is just waiting to see when/if the sale everyone is talking about is going to happen or not, which is totally fine. I think people who buy things without doing due diligence on if they can get a discount are shortchanging themselves.
