Are any Volvos FWD?
It was in the early 90s (1993) when they first came out with transverse FWD in the 850.
The 700/900 series is an old design released in 1982, but they continued to sell the same basic chassis with RWD until 1998 alongside the FWD cars- although the RWD cars based on the old 700/900s were called S90/V90 by 1998. The 700 is very similar to the 200 and shares many parts in common.
Perhaps your dad had a V70? That isn't a "700 series" and is a newer evolution of the FWD/transverse 850s.
