Those are probably THE single most popular, affordable aftermarket wheel for these cars, right up there with the Sparco offerings (some of which are no longer available it seems??).
Most seem to love their strength, low weight, and aesthetics, me included (satin black set with Conti 205/50-16 DWS-06+ on them).
But yes, as pointed out above, I seriously doubt they are being sold, even 'on sale' for $350.00 for a set of FOUR, as most retailers (even the very lowest priced ones) are getting at least $215 EACH, new, for them currently.
