2017 Nissan Sentra Incentives Question

This is the deal I ended up getting. How’d I do?

Sentra SV
MSRP: 20,115
Neg. Price: 18150.51
Incentives: 2,525
RV: 54%
MF: .00003
Acq Fee: $595
Term: 36 mo
Miles: 12k
Sales Tax: 6.25%

This ended up being $159/mo with $159 due at signing. The dealer paid the doc fee and RMV fees of $502.

Also, they offered me the “safe lease” package for $20/mo. Is this something I should consider? Apparently Nissan doesn’t do a damage waiver anymore so we will be responsible for anything above normal wear and tear. $700 for this protection seemed like a lot so I declined it but I can still sign up for it until noon today. We had $640 worth of damage on the Altima we’re returning but the front bumper was cracked and needed to be replaced.
