The 5 cylinder white blocks are pretty hardy if maintained. Just avoid the AWD's unless you are nuts like me and abscate!

My experience with my 2004 S80 FWD 12/2003-3/2016 0 miles to 110K no extra repairs needed. So 12 years 100K on a FWD Volvo is the low cost safety zone, beyond that prepare yourself to replace the entire front suspension, both axles, and all the engine/transmission mounts. Sagging mounts cause vibrations and premature CV joint failure. FWD naturally puts more torque on things like control arm bushings. Control arms are gone every 100K. Or so. My car got a pair at 110K along with both axles then again just shy of 220K. At both those replacements I had been long having pops, bangs, and increasingly hard to keep steady on the interstate symptoms.
Yup. With a manual.
