A good read here on Todd Corey's works Group B quattro. I've corresponded with Todd a few times and he's always been generous with information, dimensions, photos, etc. about his car. Best I can tell, Todd is sort of a regular guy who happened to buy this car years back before the prices went into the stratosphere. Looks like he's finally sold it and it's headed back to der Vaterland.
