There are some top notch upholstery shops in Seattle if you need some help finding a shop to do a custom job at a quarter here are a few names of great shops friends have used in the past.

Mac's Upholstery
Burien Upholstery
Rich's Custom Upholstery pretty sure this guy does all the work for the Seahawks.

I can get some address and phone numbers if you are interested.

 

Those seats are great , like the optional English Malt Brown seats of the R52 Convertible Sidewalk edition have to be the top of the list. I have only seen a handful of the hardtop versions in the first gen that have the English in Panther Schwarz.
