Lilac - that sounds like a good system.
I have a Janome sewing machine, which I bought in 1996. It is fairly basic but, obviously, a work horse :-) It hasn't been in continuous use since I bought it. It had a number of years in storage for various reasons. And, just in the last month, it has started to run very slowly when it gets hot. I'm planning to take it in to get looked at as soon as I have a week where I won't have time to see much :-)
