Hid Head lights/ Leather seats

With the HIDs . . . Don't know.

With the leather:
Sparks sells these slip-on covers: http://www.trdsparks.com/displayparts.php?Mdl_dtl=631&Part_cat=32&parts_id=2729
They sell for $399.00. That DOES NOT include installation. Though, it doesn't look too hard.

Some are nice, well made "slip-overs," meaning the cover the stock seats without bring glued on.
Others are built different and some require removal of the original cloth and new leather ones glued on to the foam.

Older cars used "hog rings" to hold the covers onto the foam and structure (I installed a set of that style Katzkins on my Miata). On the xB2, the foam is cast INTO the cloth, so there is a strong bond between them. There ARE no hog rings.

Also, be SURE the seat covers are DESIGNED for side airbags in the seats themselves. Gen 1 xBs didn't have those, ours does. Properly made covers have a "blow-out" section for the airbags built in.

Expect to pay $400-1000 uninstalled, maybe more depending on the expense of the material and if it s completely custom made. That is as opposed to a "pick the color" from a "stock" selection type of "custom" (like the Clazzio ones).

I am planning to eventually get some on my box, with the center inserts in tartan/plaid. Either they will be made with the insert or I will sew it in myself then install them.
--Oh, and in Scotland "plaid" means "blanket" and "tartan" includes what Americans call "plaid," but with more specific meaning as well. So, I seldom use the term plaid for pattern, though I do use it for a tartan patterned blanket.
