i did mine last year in leather. first i bought a leather hide from a place on ebay after getting some free samples. then i had a local interior guy cut the leather and stitch up covers based on the old passenger seat which i left him.

these covers, i then fitted myself using new cushions and straps from sunbeam specialties and some steel strips from home depot. i also did the center armrest and the GT door rolls in the same leather.

a few photos of the process here:
