I think I can explain this. The episodes were not aired in the same order they were filmed. The reasons for this could be many but I think in particular the episode Find Loretta Lynn was held back for Sweeps Week. So, we see Daisy lose her yellow car, get the Jeep and then, when Find Loretta Lynn aired, she had the yellow car again. LOL. And then I think it was another Jeep episode followed by another yellow car episode.
