John, if you're not "into it" for long enough, it's just more stuff around your neck.
After going through a similar experience with my Mom, my awareness & priorities changed a bit.
I became more conscious of making the most of enjoying my time.
That could likely result in another, better, toy that will re-kindle the old-car-guy enjoyment.
I found a great car a couple years ago courtesy of this board and the people on it, so check in and stay involved.
