Hello, the three digit code starting with 2 is leather, so 220 is blue leather. The "1" in the box after it, does it have a small "40" above it? if so then this is an option code, 401, which actually doesn't make any sense to me as option code 401 is for single seats, rather than bench seats, which Pagoda's never had. Hopefully someone may have more information on this
Regarding a source for upholstery, just search leather , using the search option above, and you'll find plenty of posts with suppliers and reviews
Good luck finding out about your (or your wife's car)
