Chicago Auto Body Parts

If you Google them, the reviews don't look very good.

I'd personally never buy a replacement fender that wasn't OE (and the ones these guys are selling aren't OE fenders). I'd also never have something shipped to me that was already painted, as there's a high risk of the paint being damaged.
 
Take a look at the reviews/complaints on Yelp and BBB.

Con artists. Buyer beware. They will send you anything just to make the transaction appear to be legit, but when the part arrives it is going to be the wrong part or damaged. I assume they go to the junk yard, grab any part they can find that is close to what you ordered and then ship that damaged part to you. I immediately disputed the purchase, cancelled my credit card and got a new card. Luckily these con artists are playing the small con and not risking going to prison by running credit cards.
