Query: Mattel Disney Pixter Cars Pitcrew Performance Playset

I can not understand how this Toy could have possible been accepted by the Mattel Quality Control and Engineering Departments.This toy is a piece of JUNK! The plastic is flimsy,the backdrop scenery panels keep falling off when cars go around the race track, or if you even breath on it, and closing it will forget it!! It does't close, it keep's popping open. I have spent hours trying to make this work, the toy is a complete failure. I can tell you this, the whole trailer is going in the trash, and will only keep the cab. If I had read the other reviews on this product I would not have purchased it. I hope I save someone else's money.
