Ask about stitch count, if all hoops are there and in good condition. Where will you get it serviced? The manual should have a check list of all accessories. Does your friend sew? ask her to try it or have the dealer try it in her presence. Was it a trade-in? Has it been professionally cleaned? Get all the services you can. I don;t have this model but bought a trade-in model and the dealer gave it a through "going over"
