Congratulations!!!!
Those look like beautiful low-mileage machines. With just a little bit of preventative maintenance (damper pad lubrication, mainly), they should last for years to come. My 1978 Maytag set had about a million miles on them, and needed a lot more work than these look like they will. Center dial Maytags are my favorite machines of all time, so I am particularly happy to see someone who appreciates them as much as I do.
