A bike is not like a car. With proper care, they can last more than a human lifespan. A 20 year old bike is far from obsolete. I say get it into excellent running condition, but don't make it pretty. And don't necessarily put as many accessories accessories as the primary bike has, at least not until the bike is proven and you're sure you'll need them. For example, I have dynamo lights on my primary bike and battery lights on most of my others. I don't have fenders on my racing bike, because I don't need to ride it in the rain.
