Depends on the model and more importantly WHEN you buy it ... lets look back a bit ... just a few Fender models that come to mind, because those are what I owned and am the most familiar with ... a MIA American Standard (and Series) bought mid 90's to earlier 2000's will currently bring ALL of the street price at the time they were new ... the early Hwy 1's are currently selling for MORE than their original street price ... the '51 Classic Series P's, as (well as the Sting in some cases), are selling well OVER their street prices when new, in some cases almost 50% more ...
... many of these, however, have taken advantage of list/street prices being raised to a point of needing to question their value/price ... in the case of the Hwy 1's, they are mainly drawing the prices due to lack of consumer knowledge ...
... with regards to the blanket comment above that Fender basses deprciate 50-60% of new, it is not actually accurate IMHO ... partly because of examples above, but also because of the way Fender has raised prices, and the value of used instruments has also climbed (with the exception of older MIM Standards) ... many of the current model (2008+) American Standards that sold for $1099-1199 are still drawing $8-900 ...
... but, with all said, if you turn basses frequently, or are buying without trying, and without the option of returning, buying right and resale can be very important ... and cautiously buying USED is almost always the best option for purchase ...
