My Volvo 240 wagon is RWD and I love it, I drive it up and down hills in vermont winters regularly.
I personally like the responsivenes it allows with a rear drive train. But I like to take turns a bit fast and enjoy the race-car feel of a box with wheels.
In terms of safety, our family has been driving this model volvo for like 10 years. My dad has a paper route where he drives in very harsh conditions in winter. We've never had any problems with bad roads, but we drive smart. If anything, the RWD makes it easier to get up an icy hill than FWD, which can be a problem on VT hills. Also the fact that I can spin the rear wheels easily in snow gives me a sense of road conditions and how gentle to drive when safety is a concern. But to me safety is more about the driver and not the car, which is why I scoff when little girls say they want an SUV because they think it makes them safe. Drivetrain really doesn't matter in slippery conditions unless you are going up/downhill or put yourself in a situation where some of your wheels may get stuck.
