Overpriced? Not really compared to their competition they are priced reasonably.
Unreliable? Nope, There are many 240’s out there with well over 300k on the clock. My stepfather traded in a V70 wagon with 250k on it, and now drives a newer V70 it has 122k on it and has just required regular maintence. My mother drives a 2004 C70 it has 110k on it and again just regular maintence.
Expensive to maintain? Compared to Toyotas and Hondas, yes, compared to BMW and Benz’s not really.
A Ford in sheeps clothing? Again no. Ford uses Volvo platforms for some of it’s cars. The 500/Taurus was more of Volvo in Ford clothing than anything.
