I picked up a beater e30 earlier this summer and the seller threw in a set of no-name sport seats along with it. I'm using them in my challenge build (not the e30) but haven't been able to get a good $$ data set because it's and older/rarer (nla) brand, "Jamex".
The seats are black faux leather, showing their age, w/ some tears in the lower seat of the drivers side.
someone found some similar ones for $50 for a miata here: http://clubroadster.net/vb_forum/21-interior-sponsored-rev9-autosport/68820-jamex-seats.html
they look very similar to these guys, just a little more worn: http://www.ebay.com/itm/Black-Racing-Seats-with-Matching-Rear-Seat-/151090503871?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item232db220bf&nma=true&si=YkSFP1l7R4SwpXebXQHjGdaM%252F2k%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
I can post pics later this evening, but based on the above, does $50 sound fair?
