Where can I get interior trip piece, like door sills, accent pieces in brushed. I dont want to pay ebay shipping on each item. Is there one place that sells this stuff. that ebay shipping is a rip.

 

mazda sells a tonne of interior items... but they seem rather really expensive... you can always check the pricing tho at your dealership

 

Generally on eBay, you'll either get a really good deal on the item and make up for it in the shipping, or a not so good deal on the item and a fairer, more realisitic deal on shipping. But, I'd rather it be kept more real (the latter) too.
To answer your question more directly, I believe there are dash kits available from the AM as I have seen some myself, but not being in the market for one, haven't really paid too much attention.
Check out the other forums, their sponsors and group buys. You may get lucky. Or, simply Google/Yahoo it!
