If people like older instruments, that's perfectly fine with me. I think it's just like collecting something, it's all about what someone else will pay for them. Luckily for me, some discontinued Ibanez basses don't demand too high a price and are pretty sweet instruments (scored my MIJ '93 SR800 for ~$179!!). For some people that's a total waste of money, but I love playing them. Taste in tone and feel is so subjective, it's hard to even compare new instruments...let alone vintage ones to new ones.
You are in the sweet spot for a collector, where your fetish object is absolutely affordable. Enjoy!
Anyone remember the rock critic Richard Meltzer? He wrote a hilarious satire on his collection of bottle caps, which were either roadside finds or stolen right off the necks of chilled bottles inside the old school dispensers. Metlzer discusses "cap collecting" in a way that makes one realize all the fetishistic behaviors of the collector can be directed toward any totemic object; the collectible is irrelevant, it is the mental process that is important and which needs to be serviced. So if you are getting it for cheap or for free, all's the better.
