My '83 240 has 192500 mi. on the odometer and still looks good and runs fine. My concern about the newer Volvos is the build quality (or lack thereof). Five cent items go bad and cost hundreds to repair. They are all front wheel drive as well.
But when I really want to get a headrush, I take the '95 E320 for a spin on the highway. :-)
