I think my Highwayman is invisible?

I've been trying to play fallout 2 and my game has been riddled with bugs but i think this one is the most game breaking so far. As the title says i never see the Highwayman i just got it from the den but when i go to other towns it never shows up.It still had most of it's battery so I'm sure it wasn't that and i haven't been to new reno or Redding or anywhere where special events could have hidden it. I just got around by when travelling clicking the see town map when getting somewhere and that made it that the car would still be waiting for me when i left town again but unfortunately when i go somewhere new that's not an option and so i lost my car going to the broken hills. Funny enough i hit lumpy with the car but there was no car idk if this is a texture issue or some other bug but is there any fix to this? I really don't want to lose this car I've already sinked 1750€ into it and a few in game hours
