Continuity mistake: When Randy is at Monk's place talking about hiring him, Monk says "Like who?" to which Randy replies "Like Me". While Randy says this he is holding a glass with one hand, the other being in his pocket. In the next shot, when Natalie says "Is it about the dentist?", Randy is holding it with two hands. Then, in the next shot, he is holding it with one hand again.

Continuity mistake: When the Captain and Randy are talking in the garage, in the shots over Randy's shoulder, the pad on his guitar strap is over his shoulder. In the shots from behind the captain, the pad is behind his back and can't be seen. (00:24:40)
Answer: Through the entire show, I don't recall her ever mentioning another job. The two explanations I had for being able to afford those cars, was there might have been a life insurance policy after her husbands death (or Mitch left her quite a bit after he died). The other may have been she had accepted some money from her family willingly or unwillingly asked for it. But in truth, I would imagine it was for product placement in the show. Most shows like Monk tend to keep the characters moderately wealthy or financially healthy, so they can insert products or items for the characters to use. Phones, food items, cars etc.
