so I have a NBP 08 TL-S and my rear bumper is cracking so I need to replace it any one know where I can find a good deal on a new bumper ?

 

like every one else, we get them from the dealership for a brand new one, which cost about ~ $250.
it comes unpainted, so you'll have to get it painted which is about another $250.

or, you could find a used one, through ebay, craigslist, junkyard, or acurazine's very own black market.
