By aftermarket I assume you mean non-Mazda branded parts?
I often look on ebay first if I need anything, but I know how frustrating it is trying to get spares - even Mazda own branded parts. Earlier on this year I could't even get an official drivers side door mirror from Mazda UK - had to buy a 2nd hand one off ebay in the end!
Yes I do =)
Same here, I wanted the sports bumper but wasn't prepared to pay the amount mazda are asking for it, possibly a second hand one that I could refirbish, but nothing. And I'm sure that aftermarket parts for the mazda 2 don't even exist. If you have an Rx7 or Rx8 then you are fine, but nothing for the two "/
