No, let's concentrate on the table structure first.

OK. It seems, then, that you need monthly prices for each car separately. As I wrote, I think it is more efficient to store information only for the months where you have changes. Then, create a lookup function that searches for the month. If it doesn't find the month, search backward to the closest month.
