Hilarious Lexus IS-F Commercial with James Sloyan

This commercial featuring perpetual Lexus voice actor James Sloyan in the passenger seat of an IS-F as Scott Pruett takes a lap around the track is just about perfect:

This is a definite payoff for using the same voice actor since the very first commercials.

(Anyone want to hazard a guess as to what James is saying right there at the end?)
