I wanna say not for that price but that's the biggest JG 1/24 collection I've ever seen on eBay though. There's some rare cars in there like the fall Dega '07, the HOS, the TMNT, the custom Farmville but again I wanna say not at that price strictly b/c most of them are commons.
There are about 5 valuable cars in that collection. I see the 2007 Cromax Pro, 2007 Cinnamon Surge, 2008 Nicorette White Ice, 2010 Honoring Our Soldiers and 2012 TMNT car. The rest are easily obtainable for a reasonable price. A couple nice customs, though.
