Old, woreout, sometimes it just time...
I relate to your story. Not 70 yet but thinking I should have the daily driver and a "toy". The way gas and insurance is, it may have to be a combination. Getting up from under the car is taking time but not painful as before I went to the chiropractor. Shoulders hurt and they are part of the reason I retired. But then I took on a project working with my arms above my head...and for the most part they are okay. Just don't overdo it. My thought is to thin the fleet and parts, put the proceeds into a vehicle and enjoy what time is left to me. AND if I don't clean up before I die, my wife has said she will kill me. Best wishes to your Grandson! Hopefully his work will not tkae him to other countries.
