When do you think they will stop selling 2017 Honda civic si's?

Okay so I'm trying to get a 2017 si by at least December or January. Because my grandpa told me if I save up a good enough down payment he will let me cosign with him. The problem is that I read online and they're are only about 2000 of them in this country (usa). I have no idea if that is true or not but I have talked to a couple of Honda salesmen and they have told me that they are limited, they also told me when I do have my money to tell them and they will look at all of the si's in this country to find the one I want(if they don't have It in their lot) if they can't find one then they will order one from Honda factory or where ever they order them from. I'm just afraid when I do go to them they'll be like "oh I'm sorry they are all sold out." and of course the one I want is the most popular one which is the 4 door black one or 4 door red one. My dream car has always been a civic si. Ever since sophomore year of highschool i've always wanted one. I was originally planning on getting the 2015 si but ever since they came out with they 2017 ones I fell in love. I use to work for Honda/Toyota so I driven one before and washed one. I'm just so scared that by the time I save enough money for a good down payment I won't be able to get one. Do you guys think by December or January there still be one for me to buy or not?

The international Model Year ends on October 1st.
If there are left overs, the dealers will gladly try locate it to sell them.

Suggestion: Buy an older model. Save your money. Pay in full.
It is rarely worth the Expense to buy New, Higher taxes, Interest on the loan, More years of high property taxes, and of course Full coverage Insurance to protect the lender.
