I was thinking that MT still owed money in it, and never paid it off so she couldn’t transfer title til she was full owner. If there had been no murder, then it would have eventually been sorted (or else MT claim it stolen or some other grift with PG unaware). Or PG just an easy sale and FD probably hiked the price on it too …
In the end, she was broke, no place to live and legal bills and she still owed on the bike …. Though I still wonder if the dirt bike was part of a version of the Gone Girl strategy at some point …
