Spare parts prices

Tell me about it! I bought a high end refrigerator in the mid '90s, about $3,500 in 1990s money. When it broke down I called an appliance repairman who deemed it not repairable and told me I was lucky to get 15 years out of it...most only last 10. Meanwhile, my mom had a refrigerator in her basement, bought in 1955 (had the old latching door handle), that ran until the early 2000s!
My parents bought a new house in 1960 and it came with a new Hotpoint refrigerator at some point it was moved to the utility room and still kept food cold when my Dad sold the house in 1994, I wonder how long the new owners kept it.
