Most of the money is for compensation - your car is now worth less money because it's either not as clean as advertised or (with the fix) not as powerful as advertised (and as unfixed). So your three year old VW is worth $15k instead of $12k - diminution in value. Costs associated with buyback, recalls, and compensation account for $10b, with the rest being various fines. Not sure where attorneys fees will be in here, but I'd imagine they are relatively low (settled quickly) and come out of the $10b pot.
Willy, I would diversify my retirement portfolio and not count on any money really. There are a couple of court rulings coming down in the next 6 months that could impact things, but I'd be surprised if any non-accident owner got more than enough to get a few suits at Joseph A. Bank. But seriously get that recall done if you haven't - look up your VIN at
