After seeing the DOTM Wreckers: Topspin, Leadfoot, and Roadbuster...i realized that the main reason for Roadbuster and Leadfoots alt modes were for advertising purposes. But if Bay was trying to use them as advertisement throughout the film, why did he choose to make Topspin a Lowe's stock car instead of the M&M stock car. M&Ms was/is a big sponsor for transformers, so why not? Topspin = Lowe's = ?? Leadfoot = Target = Hasbro's Sponsor Roadbuster = Mountain Dew = Transformers' sponsor Do you think their should be a fourth wrecker with the M&M car alt mode?
