Should you want to get yourself a classic MX-5 Miata on the used market, prices are changing fast! Some years ago, you could easily buy a pretty good NA-generation MX-5 Miata for around $5,000. These days, however, the demand for modern classic cars like these Miatas means that the very same NA Mazda Miata 1990 could now be changing hands for about $15,000. Although, slightly worn examples of an NA can still be had for under $10,000 if you look hard enough. If you want a good, somewhat vintage MX-5 for cheap, you could look at the NB-generation Miatas. These were built from the late-90s to the mid-2000s. You can find really good examples of this selling for around $10,000, sometimes dropping below that. So, if you don't mind missing out on the O.G. NA Miata, the NB is still pretty great.
