[Tajefe Couple]

Sorry to here about the situation at all.
I'm not in your shoes but have six toys that I can not drive due to multiple health issues. I'm told can possibly expect a shorter than average life span by 10-15 years. I live in pain every day even with all the medicines and treatments. Some days better than others. Currently I'm not capable of driving due to another health reason. I keep every toy anyway. Even thinking about getting another. Not everyone understands why I keep them but cars have been my passion since could walk & talk. Keeping the toys still gives me hope that perhaps someday will again be able to play with them. That might never be the case but I like my toys and just sitting in my shop for some reason they bring me pleasure and hope. I also have enough loving grand-kids to pass them along. Want those kids to get the joy I did from them and maybe think of me on occasion while doing so. That said the grand-kids keep me going more than the toys all the time not even close. Really like and enjoy the toys but very much love my family.
My situation is no way the same as yours and not trying to compare it. I currently still have the means to keep material things and get the medical attention I need on a regular basis. Even so if put in your situation I wouldn't know what to do. Have always said if needed and they could find a way to make me better I'd trade everything material have to be in decent health again with no more pain.
I would think that at this point it's your caring that helps him and not the car any longer. My wife helps me get on this forum and with much more. She knows how much happiness I get from it and my passion for anything with tires and a motor. What I've never told her before now it's more that she cares enough to do what she does for me.
None of what I said was probably helpful. I can't imagine being in your situation, and no way trying to advise you what to do. Just sharing my story.

God Bless best wishes and happy thoughts your way!
