My 8880 Super Car: Quality criteria for potential buyers?
Besides the obvious quality checks, something that is quite important to me when buying second hand: in what state of assembly will the set be shipped?

Unless it's a set I'm desperately searching, I will almost certainly forego bidding if the set appears to be shipped entirely assembled.

Partially disassembled is even worse in my opinion. 

Also not acceptable is the set entirely disassembled but all pieces thrown together, I believe this causes scratches on the pieces and makes it easy to have pieces missing (with the mistake possibly happening on my end while resorting the pieces).

Ideally the set is shipped entirely disassembled and the pieces sorted in zip-lock bags in a logical way: large pieces with large pieces, smaller with smaller... In such a manner that it's easy to check for completeness and I'll have fun rebuilding the set.

Problem is that the shipping manner is seldom described in any online advertisement, one needs to ask for this...
