I loved Volvos too. We sold because the maintenence cost was exhorbinant and space was limited.
If you can afford the parts and labor, AND an aftermarket warranty, I think you should be good if you plan on keeping it. They do not hold their value very well so you're on the good end of things if you look at a used one.
The safety is decent-good for a sedan/wagon. The car seat installs can be very difficult and the BV was a bit too large for the car so we had to buy a Diplomat in order for a passenger to get in up front.
There are some key things to watch out for in them mechanically- namely the AWD systems (if you don't live up north I would recommend a FWD version) - and some of the transmissions (avoid 2001 year models). Both are costly and repairs could easily cost as much as the car itself.
If you are needing more specific information, feel free to PM me, or ask here and I will try to get more information for you.
ETA: We got a 2004 Sienna XLE Limited. We will not be buying another Volvo as our main car, for what it's worth.
