The 2007 IAA Hall 2 is dominated by one brand. Mercedes-Benz. It is a fun place. It is the most impressive hall; and is probably the most populated hall per square meter. Once you walk in, if the light and sound show have not already taken your attention; the display on the wall size TV; or the architecture of the structure certainly will. That is only before a McLaren SLR Roadster or the AMG C63 smack you at your face at the entrance.
