Their photo does not depict the actual seat covers, so here's mine, installed in about 5 minutes. They have a decent color selection, and the only ones I could find in purple/black.
The back row covers are "not available yet," according to customer service, but the gent I spoke with gave an ETA of 2-3 months.

P.S. Now I need to chase that thread about the custom headrest embroidery to get my purple/silver SS logos sewn on the headrest covers.
