Oh Patrice, you're asking more embarassing questions! LOL I bought this machine in either 2001 or 2002, at income tax return time. hehehe I have never taken it in for a tune up or service of any kind.
I used it a lot from the time of purchase until August 2005. Then I pretty much took a 3 year sewing hiatus, and started sewing again in August 2008. Those three years I was living in Hawaii and wasn't interested in sewing at all. Sooooo much else to be doing! :D
