Once you're ready to spring for a used MX-5 Miata, make sure you're diligent. That's especially so if you're buying one of the older MX-5s from the 90s and early 2000s. These cars were well-known today for rust issues and frame-related wear and tear. This is typical when a car's aged 20 or 30 years. Therefore, wherever you're buying a Miata from, a quick look around at all the trouble spots for rust is recommended. In particular, take a closer look at the footwell (you'll have to remove the carpet first to get a better look). Then, pivot to checking the door frames, including the bottom and inner lip of the doors. In addition, check around the rocker covers, bumpers, and fenders for signs of corrosion or other frame/body damage.
