Here's my advice that can be applied to many basses (especially Fender's!!!!): Try it before you buy it!!! IF not, make sure there is a good return policy!
Marcus nailed this one. I picked up a 2002 MIM Jazz Standard that was in "like new" condition (one 1 mm "less-than-ding" on the back of the body) that led me to believe this was purchased for someone who wanted to play bass, and then sat in the closet or under a bed for 4 years. Besides the absolute killer condition it also resonated like a songbird
unplugged, always a great sign. I grabbed it up for a price so low that a good deal of
my friends here would throw a punch at me for (

) but after upgrading the bridge, pickguard (White Pearloid on Midnight Wine = Tasty!), pickups to Bassline SJB-2 Hots, and a good set-up it's now become my fabulous "Passive 4-String" that my collection needed for both tone, recording purposes (sometimes you simply need a good
passive bass) and the calling for a 4-string that my was being whispering to my brain for a while at that point. Next set is upgrading the tuners to a higher-quality set as well as a Hipshot Bass eXtender, but that can wait for a bit as I'm not gigging currently.
Point being, I had played a
great deal of both MIM, MIJ, and MIA locally over the past few years and can totally agree. I played MIAs that were fantastic and in hindsight wished I had found a way to purchase (an amazing American Deluxe Precision 5, anyone?

) and MIMs that has no resonance whatsoever... but also the reverse, MIAs that had no buisness being so, and MIMs like mine that were great "platforms" to be upgraded (and honestly, was certainly gigable in it's purchase state). Just be prepared to "shop around", or if you're in the position like me where you have to shop via online store (in my cases, it's because I purchase on MF.com's credit and for the most part am stuck to them for my purchases) be ready to ship a bass back if you're not sastisfied (although it's all of $12 to ship back FedEx Ground, so that's hardly a backbreaker financially).
