2016 Kia Optima LX 1.6T 24/12

What is the MF and residual for a 24/12k lease on a Kia Optima LX 1.6T with the Technology package? I will be shopping in Los Angeles. My credit is approx 700

The MSRP is $24,140 (+ $2600 for tech package)

Kia offers -$4,000 special financing offer for the Kia Optima LX, as well as a $500 end of year offer.

If I pay $0 down, the kia website says my monthly payments will by $253/month. How much negotiating room is there on that number?

Is it worth waiting until the 2017 Kia Optima (non-hybrid) comes out?

This is my first time leasing a car, so I really appreciate the help!

Numbers look ok, there could be room for more discount (and lower payment, maybe closer to $200 mark)
