May I 1031 exchange a Section 179 SUV?

And if so, what will be my allowed tax write offs &/or Tax liability...

In October 2017 I bought a $25,000 used SUV; (100% for business use, and I plan to take a Section 179 deduction for $25,000 on my 2017 tax return); and then...

In January of 2018 , can do a 1031 exchange if I trade it in for a $45,000 used SUV (Used 100% for business in 2018);

Would I also be able to write off any (or all) of the additional $25,000 out of of pocket paid for the newer, traded in SUV, in 2018, ($45,000 purchase price minus the approximate $20,000 trade in value of the original SUV) as a Section 179 Deduction?

Thank you,
