Wow, this surprised even me. On Sunday, I placed an order with Miatamania.com. The next day, I received their catalogue in the mail, and the following day (Tuesday) I received the part I ordered! Miatamania has a California address and I'm in Canada! I wish my own company could be so efficient.
The part was a cup holder which goes on the floor mat edge and it seems to fit very well (actually matches the interior and looks like it belongs there).
ps: For cross-border shopping (at least US into Canada), using UPS 2 day expedited saves the much more expensive brokerage done by the Canadian postal service.
