For scrap you can check Sharjah new scrap. Location: http://bit.ly/2o60N5L For new you can check Sharjah bmw road or Dubai Deira market. Shops like Majelan, Divya, Western Auto can possibly arrange them for you.
I am looking for an original (stock) exhaust for a SC400. Sadly most of the shops mentioned do not have it in stock... but wondering if anyone has it just laying around or knows a place (even scrap?) to find similar parts.
I've yet to look at the sharjah scrap area mentioned here.
