There have been multiple McQueens over the years that lack the front-of-the-spoiler "Rust-eze" logo -- yet Mattel has never fixed them for whatever reason in later releases. What I've done is create customs for those, by blending a body that has the spoiler logo, with any frame or paint job that doesn't. Thus I have a dirt track McQueen with spoiler (I did my own dirty overspray), or a regular 'Dinoco' (regular wheels and axles on a 'Bling' body, IIRC).
For the Autonaut McQueen, the 'clean' version is him hurtling through space, and the burned version is him after splashdown. Sneaky Mattel making us buy him twice!
