I know nothing about it, but a person about 1/2 mile away from me just put a For Sale sign on their Miata yesterday. Looks pretty clean, but I was standing on the berm of a pretty busy road and didn't want to get killified. Manual, white with either black or charcoal cloth. Wheels, possibly lowered, hootus-compensation-style spoiler, rimz. I did notice a cracked windshield on the lower driver's side.
I texted the number (assuming it's a cell because that's a Brooklyn/Queens/Staten Island area code) and I'll add details if they get back to me. I'm willing to check it out for anyone gratis, but I've never owned one so you'll have to tell me what to scrutinize. I'm at least mechanically savvy so I could identify obvious problems.
