Think the only way they would come after you is the fact that you are a car trader (legitimate or otherwise). It wouldn't be too hard for them to establish that you buy and sell cars and the fact you want a recovery truck would obviously back this up
I reckon they would suss out what's happening and repo the motor regardless of the "story" or any fake receipts knocked up etc - finance companies are not that stupid (I used to work with a guy who had his own cargo and repo'd motors for a living - you would be amazed how much info they can get their hands on )

IMO
