A class-action lawsuit against the city of Minneapolis over its handling of impounded-vehicle auctions has led to advertisements that tell people they may have money coming if their car has been towed and auctioned off in the past seven years.

The sale of those forgotten or long-lost vehicles created a pool of cash worth at least $770,000 that, under state law, the city must return to people who had their cars or trucks towed to the city’s impound lot and then sold.
