I think he's just fascinated by certain things. The Phaeton is an amazing car and outside of VW's normal lineup. The Hilux is huge all over the world, and virtually unheard of here. And yes, the Jankel armored version is pretty impressive:) Having met him, I HIGHLY doubt he's paid for product placement. I think he's just INTO things in a very geeky way. He focused on Curtas more than Phaetons anyhow:)
Yeah, I concur. He's talked about it on Twitter (people have asked why he mentions specific products) and he said that he just likes to include things he finds interesting. I think for the current trilogy it actually works really well, as it keeps everything grounded in reality.
