Hmm it will usually cost about $800 for a complete set of bodykit to be shipped to your door...
Putting it on isnt hard, i did mine when i was 16, and i didnt had no help... just took about 6 hours just for the front bumper and took about 30 minutes for the sides and 2 hours for the back... The front was the SHIT...
Dont buy crap bodykit that is on ebay, they are made outta fiberglass and they break and they chip and shit..
Buy from ground dynamics or something, oh also, get FRP bodykit, which is Fiberglass Reinforced Plastic..
