Generally I think it will be okay. I'm not familiar with that model, but have a Raliegh Team USA from that time. I think the biggest problem will be with getting replacement parts. But if you haven't ridden a lot there shouldn't be any worn parts to replace yet. One thing to consider is the wheel rim material. If it's aluminum, no big problem. If stainless steel, then maybe you might consider up grading them as brakes don't work as well on stainless steel rims when wet. The tires are probably 27" tires and you can still get them, although not as much choice of different tread patterns and materials.
If you plan to ride it, at least have the LBS give it a tune up when replacing the tires. Selling might be harder. There is a demand for old bikes like that for people to convert to fixies, but it's not going to be a high dollar because it's mostly for the frame. I checked eBay's past auctions and they all were after year 2000 models. So I have no idea on price. Yes, technology has changed, but there has been more change in standardization of parts (screw threadings, tube diameters and such). But as far as "dying just because you rode an old bike" goes, remember this. There are people who buy old steel bike frames because they think they are sturdier than new ones.
