Someone at my company selling his Miata - 1990 Mazda MX-5 Coupe for sale by owner - Holliston, MA - craigslist
~123K miles. He's asking $5,500k - not sure if that's on par with other NA Miatas with a hard top and some rust in the rockers, or if he's dreaming...
This corner seems to have the worst of the rust - the others look slightly better...
