One is a loan and one is a flat out purchase. On the loan, the terms and conditions can change. Even on sales, if a product you buy goes for some special price, generally when it comes to retail you can get a price match for 30 days. When you say it simply "what's the difference", then it seems that way, but in reality there's a lot more in the finance of one than the other.
Why didn't you phrase your question "You buy a $3000 TV one day, and then the next day it's on sale for $1500." Because we all know that you could get $1500 back if that was the case and it's the same with the car. Not a good that you've consumed like gas, milk, or yesterdays burger.
most stores will refund you money within 30 days if the price difference is significant enough. bug as BIGGY pointed out, giving gas prices as an example is ridiculous. what matters is purchases that actually cost you real money, especially when you finance them.
