No, not in most American states. We (mostly) use the UCC in our states. The seller (legal term in this instance that means the guy who bought it from snap on and is now selling it to you) is selling to you the buyer.
If you the buyer purchased in good faith the legal question is whether you had notice. Notice is done through the UCC filing system in each state, usually through the secretary of state. In other words, did the creditor (say snap on here) properly file a UCC notice. Since revised article 9 came out about 10 years ago, this also means did they properly comply with the model search logic--which is its own legal/admin question for court.
Anyhow, before you the buyer buy you need to check the UCC system for the seller. If there is a filing, don't buy. If there is a filing, made properly, and you didn't check or you missed it, things start to get bad.
Depending on the state, so this is a general overview, your state may vary, if the creditor had a proper filing and you purchased anyway, you take ownership of the tools/box with the same title the seller had, a voidable title. That means the creditor can send someone to a place of business to try to pick up the goods in a peaceful manner. In some states they can also try to do that from a home--but not as many states.
The creditor, their agent (the repo man), or both are on the hook for illegal activities during the repo, including breach of the peace. In other words, if the snap on guy finds out you purchased a box from his customer and comes to your home and starts kicking the door and yellling the cops are coming to arrest you, video it--you have hit the legal jackpot.
The proper legal step for the creditor is to file--what most states call--a claim and delivery action. For example, snap on finds out you purchased a box from one of their customers, they think they filed the UCC correctly, they sue you with the goal of the suit being a court order against you to turn over the box. During that suit you get to argue something back against the creditor--most of the time in these suits the argument is they didn't file correctly (that model search logic stuff) so 'I wouldn't be able to find your filing with a reasonable search'.
If the creditor 1) screwed up the filing or didn't do one, and 2) you acted in 'good faith' as part of the purchase (a legal concept and term of art just for the uniform commerical code--but at its heart you acted as a reasonable and honest buyer would and you paid a fair value)-- then you as the buyer get better than the seller's voidable title, you get good title even against the creditor.
If you get the good title legally, then the creditor is out of luck as far as your tools go. They are reduced back to suing the seller for the money he owes them.
The lesson here? Check the UCC before you plunk down 6k on a box of tools, keep the results of that check, and get something in writing from the seller showing that you paid some reasonable amount.
