The marked chassis appears to be in excellent condition. It is highly detailed as you can see from the photos. I tried to take pics from all sides so please view carefully as these are part of the item description.
The only flaw I noticed is there are some gray marks on the tires, perhaps from being displayed.. These may clean off, hard to say. The rest of the car appears to be in excellent condition.The extra unmarked chassis appears to be in even better condition. It still has some protective material around the tires, so that suggests to me that this chassis was never used or removed from the box. Colorful box is in excellent condition with a little storage wear to some edges and corners.
