The original Mazda Miata 1990 is a highly sought-after vehicle. So much so, that despite Mazda selling hundreds of thousands of them worldwide, they're still pretty valuable even if they're somewhat regarded as commodity items. Granted, this is partly because of the rarity of trying to find a Mazda Miata 1990 in good condition. These early units suffered from numerous rust issues, among other bodywork problems that appear as they age. Plus, after more than 30 years, it's common that a 1990 model year example may have developed other faults along the way. As such, these factors - mainly mileage and condition - have driven up the original MX-5's market value. According to Edmunds, this 1990 model could be priced at anywhere from $4,700 to $7,300 on average today, depending on their spec and condition.
