Personally I like the manufacturer extended warranty on any vehicle I buy now. Generally speaking, there is so much that could go wrong with new cars these days. My 2011 sierra is covered until 10/2018. zero deductible.
If anything, at least cover the term of the loan with an extended warranty. That is the last thing you want to do is to pay for an expensive repair while still making payments.
Like the price of the vehicle, the extended warranty price is negotiable. I do not like aftermarket warranties, to many loopholes and items not covered.
Best of luck to you.
