I see good old sibling rivalry is alive and well.
I have an older sister by 3 years that destroyed any meaningful friendship we could of had over the years.
What a waste. I would have loved to have had a lifelong friendship with my only sister.
Call your sister and tell her if she needs any help with the old jeep to give you a call. That jeep will be long gone someday but your sister will be your sister till the day you die
