It makes no sense to swap for a Ford based Volvo if you want "Volvo reliability" , I found changing my Mk3 Focus estate for my V70 D5 was a great move, its bigger, if anything better on fuel and has far better performance and thus far has been pretty much faultless.
The P2 V70 is from a time when Volvo made Volvo's, without Ford accountants spoiling the brew, and it shows, to quote Wiki "Critical aspects of the design for the second generation were completed before Ford acquired Volvo in 1999" which is telling.
