Sorry to hear that happened to you. I kinda know what it feels like.
A few years ago, I parked my car on Balmuto, just outside the Manulife centre to hit a bank machine.
I came out 15 mins later, ...and my car was gone!
Wasn't stolen, ...just towed. Those mofos wait around the corner, ...and the minute the clock strikes 5pm, they start towing. Even tho it wasn't stolen, I thought it was for a while so I know the initial anger you feel.
Hope you get your full purchase price.
