But, back to this guy's original post:
Nothing from Autos International is cheap, but all of it is good. $400 seats from Vintage may or may not fit your butt. If they do, fantastic.
But every guy I know (no named Jack Crosby) who drives 750- 1000 mi in a day does it in seats that cost a heck of a lot more than $400/pr. Widebody guys have it easy, as nice Gen 1 Miata seats will fit, as will several different high-back race buckets and some old Recarros. If a guy wants a more "old-school" look, the choices winnow down a bit.
The price for a set of Fibersteel buckets, in the (wider) OE width, upholstered in leather with molded foam was $2500 several years ago. Call it nuts (it is), but that's what it cost me to be comfortable.
To the larger point: could we please (pretty please?) stop cutting down every single "for sale" post that isn't a "fire sale" post? You don't want it? Don't buy it, but taking a swing at every last one is kind've counter-productive.
