Hey,
Go here:
http://www.carbra.com.au/
The car bra is tops, the ppl selling it are absolutely brilliant, couldn't recommend them more highly. I sent my new car bra back 4 times for alterations and they didn't charge me a zac, not even postage. The over all cost was $400 + $40 for having GTST embroidered on the front. {Not shown in the pic, on my new car bra, pic shown is 4 years old, I replaced this bra cos I bottomed out on a gutter and there wasn't enough race tape in the world to fix it.}
I live in country NSW, bugs, locusts, gravel, dust, sand so a car bra was essential for me.
