Musical instruments are like any other consumer goods: When you tally up the 10's of thousands of new basses made every year, there's only going to be a handful of best sellers that may or may not be 5 or 10 years out.
Think of the Shark Tank that is the 'Vintage' market: Gibson, Fender, Martin, and a lot more have made thousands and thousands of instruments over their histories, yet only a handful are true collectibles with big ticket prices. Chevrolet has made millions of cars, but you rarely see anything past a '63 Split-Window Vette, a '57 BelAir Convertible, or an SS or Yenko Camaro pulling down the big $$ at auction. Your uncle's C10 and your aunt's Impala she drove to church will go to the crusher without comment. Guitars and Basses are the same.
Any new bass is being bought at roughly 1/2 of retail full list price on a store level, maybe a bigger discount for the huge chains. That's roughly what it's worth after you buy it. Now having said that, some things will fare better than that in the short term (recently discontinued, rare color, demand was higher than production expected) and some of them will fare worse (virtually any custom, 'boutique' bass, or some really doggy, plain, cheapo off-brand piece).
So your best bet is to NOT get your blood up, get a bad case of GAS, and NOT shop around, take your time and see what's out there. I prefer 'open box' or barely used mint. The last thing I'm going to do is walk in a store, swoon, and pull out the card while I'm sweating, the room is spinning, and I'm deep in the throes of "I Gotta Have It Now!!!!'. If you settle on a certain piece, you'd be amazed the range of prices you can find given a 90-day period of watching the market. Buy as smart as you can. They're tools.
