Does anyone know when Lois acquired her Jeep? And do we know whether she had a car before that, or is it cannon that she just used cabs?
She's driving it in S1 during the ILTY when they go to visit the Morrises (Mr. Invisible). She also has it in IoM, when she's kidnapped by Eugene Laderman (hiding in the backseat). I don't know when she got the vanity plates of LL, but I believe the first sighting of them is in S2.
