i want to get a m3 lip spoiler but i want to know if you can tell a difference between the rubber spoilers i see on ebay or the real genuine spoilers taht cost a $100 dollars more. i'm tryin so save some cash but i don't want to look tacky

 

I got a rubber spoiler to color match my car from ebay. Looks fine.

 

i got the rubber spoiler to match my audi also and it looks awesome.
