My two Chessie and single Cargill cars arrived today, pretty much what you'd expect from TWX, very well made cars. They do come packaged a little differently than previous TWX cars I've bought were. Same jewel case, same nest, but the jewel case was wrapped in plastic and the car itself was wrapped in plastic that has a light adhesive on it; the car doesn't just slide out of the plastic, you need to pull the plastic apart at the seam to release the car and the adhesive (think of postit note sticky) is on the entirety of the inside of the plastic, contacting the car.
Not sure if it's good or bad, but it is different from previous releases.
