I've got two used sets for sale, one 99.9% complete, one 100%.
1. LEGO Technic Tow Truck 8285
The truck is in amazing condition, built once and never played with. Although, a couple of parts are missing - probably due to shifting it from shelf to shelf.
MISSING: Parts missing VISIBLE IN PICTURES on eBay: 1x right rear view mirror (3 pieces with sticker)
1x exhaust chimney (5 parts)
I think all other parts are there, as I have no time to check part for part. At first inspection, the only things seemed missing were stated above.http://www.ebay.com/itm/300948175652?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
2. Mindstorms NXT 8527 - Complete
The same as the truck, built once - never played with. Amazing condition.
Comes with the user manual, the spare tires, the Red Ball, and the extra parts not pictured.http://www.ebay.com/itm/300948182419?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
