Just Got My New '05 Hid Headlight Housings!

[BlexusGS]

The ones with the green tint. Having them installed on Fri. Probably going to sell my old housings on Ebay or something. About 3 months ago I noticed that one of my headlights weren't auto-leveling at night when I turned them on. Went to get an oil change at the dealer and asked to check out the problem. Sure enough the auto-leveling mechanism was broken. They had to replace the entire housing! Good thing it was covered under warranty. It wound up costing $1,100.00 with the part, labor and tax; not a dime out of my pocket. :P But now I had one brand new headlight and one noticebly old one. This is what prompted me to upgrade to new on both sides. :) How much do you guys think I can get for my old headlights? One is only 3 months old (like new; no scratches) and the other is great condition (which I am also going to do a 3-stage wet sand).

Also, off topic... I restored my old stock exhaust from my car to like new condition (it shines now). How much would you suggest I try to sell them for?
