2.31. “Eligible Seller” means a person who purchased or otherwise acquired an Eligible
Vehicle on or before September 18, 2015, and sold or otherwise transferred ownership of such
vehicle after September 18, 2015, but before June 28, 2016. For avoidance of doubt, Eligible
Seller includes any owner (1) who acquired his, her, or its Eligible Vehicle on or before
September 18, 2015, (2) whose Eligible Vehicle was totaled, and (3) who consequently
transferred title of his, her, or its vehicle to an insurance company after September 18, 2015, but
before June 28, 2016.
So if you had transferred title prior to 6/28 then you'd be a "seller" and would receive 50% of the "oops" money or about $2500.
11. Can I receive benefits if my car was totaled after September 18, 2015?
If you owned an Eligible Vehicle that was functioning and operable as of September 18, 2015, but was
subsequently totaled (and the title was transferred to an insurance company), you will be eligible for
benefits under the Class Action Settlement as described in this notice at Question 19.
There is one
exception: if your car is totaled after June 28, 2016, but before the opt-out date (September 16, 2016), you
are excluded from the settlement class and reserve your rights and claims against the Volkswagen entities.
So if you hand over the car to the insurance now you are out of the settlement completely. At least that's what it currently says. I'm definitely not a lawyer but it seems pretty clear. You either total it and let the insurance company take it or you total it and pay the salvage value to keep it and then get it running asap.
