2017 Hyundai Elantra Value Edition Deal $88 Per Mo

Inland Freight & Handling: $835
Total MSRP: $23,860

On Tier 6 Credit (not a lot of credit history, first lease, score low 600s), do NOT have the MF for this, assumed .002 4.8% (for Tier 1, I think .00016 0.384%)

I think I am missing the $3,000 lease cash to make this deal actually work. Would you guys know where I can find this? Found a $2,000 Bonus cash but not sure if stackable with the items above (worth $55/mo)

Any dealers in SoCal (Orange County) that can help us with the $2,000 bonus @ $55/mo and then trade in $800 (old Elantra) @ $22/mo = $292 - $77 = $215/mo is probably something we will be happy with
