Hey I am wondering where the best place in sa or the best website is to get parts for an mr2 sw20

I'm looking for most body parts in red and some of the targa seals and interior

Cheers in advance

This is the best website to find parts. Finding the colour you want isn't always easy, and with red you're pretty much pushing it uphill to find the right 'shade of fade' to match what you already have.
 
Targa seals can still be bought new, someone will chime in with their favoured supplier soon enough.
 
There's a member here, DB8, he supplies them new I think. Could be worth PM'ing him.

The where do I go list;
Get along to local club meet ups and meet guys in your state who many have the parts or guide to what's best places for your state/area
the forum : check out the for sale and/or post a WTB want to buy
there are a number of forum supporter / guys who have taken the hobby to another level with many many parts who can sell you what you need (like mr2 parts Australia)
Facebook pages for mr2 parts trading / mr2 related stuff
there are importers of quality second hand parts (like gorilla industries, DB8)
Gumtree
Overseas like twosrus (USA) and benmr2 (uk)
Amayama (Japan/overseas new parts)

Road and Track, Qld often have hard to get MR2 stuff.
 
 
 

I just brought some targa seals from tworus. I didn't look anywhere else for them as I had to get some other stuff from them as well.

Have also used DB8 and Gorilla industries and highly recommend both

+1 for Gorilla Industries, can get most aftermarket stuff your after at a good price shipped to your door.
