What model is a fender stratocaster with a serial number mz0189472?

The model is Fender Stratocaster! The MZ in the serial number identifies it as a Mexican made Stratocaster made in 2000/2001. If you're asking if it's collectible then the answer is probably no or at least not at this time. If you're asking if it's a good guitar then yes it's bad at all, but the Mexican strats are considered to be inferior to their American made cousins, but again they are pretty decent Guitars.
