That would have been a good investment. Not that you'd have any chance of knowing it at the time.
I knew, and bought a few. If you're okay with keeping things around a few years, you really can't go wrong buying an older, desirable instrument. Don't look for resale value in anything that sells new at GC.
Here's a short list of good buys right now. Remember, don't pay gbase prices. Search craigslist, look for a bad ebay posting, make someone an offer who has one of these basses laying around. They will appreciate.
Late 70's Musicman Sabre, around $1200.
Late 70's Rickenbacker 4001, around $1200.
82-94 Fender basses, any of them: USA, Japan, reissue, etc. You can get these dirt cheap. I just scanned craigslist near me and saw a few. You'll know if it's a good one when you play it.
If you just need a cheap, decent bass that will stay the same $100 value; buy an SX, USA Peavey Fury, etc. There are plenty of cheap, very good basses around used. I visit GC regularly for strings, sticks, etc. I scan the bass racks, and there's not much good there. The new Fender basses are better than they've been in years; but they'll loose 30% of their value as you're swiping your card.
