That is exactly what I did last year. Bought a low mileage 2003 9-5. Treated the whole process like owning a commercial aircraft where replaced as part as possible to start fresh. Easier in this day and age, with internet helping on guidance and parts. I am not a car guy overall, though average auto design, external and internal, low-priced or expensive, is like fingernails on a chalkboard. Saab was about only thing that was calming for me.
