I am not so sure if it was SS's MO to be driven around by his chauffeur in the Mosler. The reason for him to have a driver is so he can work. Not so that he can have an exciting ride. I have no idea for sure, but I am guessing that the beauty of the Mosler is driving it, not being a working passenger. SS might have let JW take it out for wash or short spin, or one or two commutes to work to experience it. But I highly doubt this was so day-to-day that JW would need his own expired reg. I could be wrong.
If he would need an expired reg as better than no reg, why would he keep it in his backpack in his OWN car? If garage is locked, possibly has alarm (surely car does) and he has to take it in for maintenance or to be washed, why wouldn't SS keep the reg. safely in the console or the glove compartment. I'd think the Mosler was kept locked, so another layer of protection. I don't know that JW would be given access to the Mosler, keys to it, code to garage, be put in charge of the fleet. He's a part-time driver, a new employee. AGREED. The Mosler wasn't SS's commute car. These terrifically expensive cars are investments, pride and joys, treated like babies. It would not surprise me if SS had someone other than JW who he called in to take care of the fleet. If not, he sent the cars out to specialists, either driving them in himself or having them picked up.
I think the idea that JW is given the Mosler reg., location of its keys, the house alarm code, hand-picked to deliver 40 thousand dollars in a life or death situation, underestimates SS's experience, acumen, caution, judgement. Sure, he was giving "the personable kid" a chance, sharing a mutual enthusiasm for performance cars, especially a beauty like the Mosler, and kind enough to credit JW's knowledge by asking him how it felt in the test drive.
A few months on the job, JW was in a probationary status. Hence, knowing JW was just a glorified assistant/driver, the accountant did not take bring him in on the bank transaction. He claimed to witness it to demonstrate SS's faith in him so as to explain his being chosen to deliver so much cash.
He lied about the Wednesday text from SS's cell because it was not from SS, but from a kidnapper in the house keeping him posted as to the plan.
I believe JW not only lied about getting a text "from SS" on Wednesday night, but he first claimed SS contacted him in a voice mail. I don't think that is in the CD, but a police source is cited in a news report as relaying that SS, confronted with his own phone, had to admit "SS' (his CELL) left instructions in text. That lie was to cover that he was making plans with one of the kidnappers, not the boss. He pretended he heard the boss's voice. And he was distancing himself at first from what was going on Wed. night in claiming he got pulled in not until the Thursday a.m. "flurry of calls" just like anyone else.
I don't find his lies merely suspicious. The lies he told are explained by his involvement as they were 100percent related to masking it in every case. No alternate explanation makes sense anymore. JMO!
