Im a little confused, as to why you would let this drive your purchase decisions. As said before, it’s about who’s name is on the title. If your after something to clarify, it’s not his Jeep, have a windshield sticker made that says “NOT (BIL NAME) JEEP”. Seems silly to go blow a pocket full of cash on something just to clarify its not the previous owners Jeep anymore. Then when it all blows over, peel the sticker off. What did you waste, 10-20 bucks vs a new hood, or hood mods you may not be happy with in the future??
At the end of the day, it’s in your driveway right? So it’s all about what YOU WANT. If your into the hood mods, go for it, but don’t let petty stuff like that drive your decisions...
Also, is it a possibility that they keep referring to it as “his” Jeep because it bothers you so much? Just food for thought..
That’s my .02 on the matter. Take it for what it’s worth. Good luck with YOUR build!
