I try not to take my much-loved Bernina in. It's been so many years, I might have to do it sometime in the next few years. Everything works wonderfully well, and I do my best to keep it clean, but I know there are interior parts that I can't get to. If and when I do take it in, I don't have a lot of choices if I want to keep driving time reasonable. Even so, I will probably drop in at the dealership and chat a bit with the salespeople to get a feel for the quality of the techs, turnaround time, etc.
