I seem to be the king of the thread derail lately, so apologies,
@mimico_polak !
I can't speak for the one guy (my mother's cousin-in-law, no idea how to properly describe that) I know who owns one directly, but what he told me was that the V8 Miata made driving his tubular frame Cobra kit (which cost triple the Mazda) seem a bit dull. Used Miatas can be had cheap, especially if you don't care about the drivetrain.
I suspect a huge part of the appeal is simply in the fact that it's a Miata. There's a track test done by someone at one of the mainline US car magazines that I read a while ago where the author was positively giddy about the driving experience. He wasn't fussed about lap times or cornering speeds, just in the sheer joy of whazzing it around a track. Definitely not a high mileage vehicle, but when I read that a Miata and a Mustang were being cross-shopped, it seemed like a deeply inappropriate compromise between the two...
