Again, does not include shipping. These are just primed though, will require painting.
Also, do note that this is for bumper only...you will need the lower grills, airducts, and possibly new screws.
Save some hassle and buy it here for $900,

but I'm sure it will be cheaper if bought separately not as a "kit"
