Someone owns two AMAZING Volkswagens

I found this house last night while out for a run, and I've been buzzing with excitement ever since. Looks like a garden-variety Passat and Touareg, right? Nope. That's a Passat W8 and a Touareg V10 TDI. Holy shit! I wanted to knock on the door and find out who this mysterious VW nut is, but I didn't know if that would be weird.
