My 28(m) truck was stolen from a performance shop

My truck was recently stolen from a performance shop in Houston. Talked with the manager of the shop and he said that the police are trying to recover the truck. The video was turned into HPD. I highly doubt that they will get it back. I made a separate police report and now I’m planning to sue, for the amount of money I spent for the work. How do I go about this? I’ve spent around 15k on it.
