$795 for 17inch silvers sounds very dodgy, especially if you take into account that you are purchasing them off someone elso so there is a mark-up involved, meaning they must be even cheaper than that to someone else if you get my drift.
If I dont get the rims from overseas myself I purchase them off a very reputable company, to put in comparrison my 17inch silvers are $1050 but come with a 1 year warranty and wheel nuts worth $80
I have an extensive online catologue so let me know if you want the link by messaging me
cheers guys
