Quote from site: Owners receive their Vehicle Value, plus an additional cash payment (“Owner Restitution”). The Owner Restitution payment is calculated at 20% of the Vehicle Value plus $2,986.73. The minimum Owner Restitution payment for any Class Member—to be paid on top of the Vehicle Value—will be $5,100.
This clearly says vehicle value, so what you calculate after mileage plus the extra cash.
I am fairly certain everyone getws cash on top of the buyback. ESPECIALLY since those specific words were in the deal they proposed to breyer. He aint gonna let them slink away without the buyback PLUS "Significant compensation"
AND: "If you choose the Buyback option, you will receive your car’s September 2015 Clean Trade Vehicle Value, plus a cash payment, ranging from a minimum of $5,100 to nearly $10,000, depending on your vehicle. "
So spreadsheet for actual buyback value PLUS however much extra you calculate for (Vehicles value * .2 PLUS $2986.00)
