After I heard the exhaust note on a Milltek S6, I fell in love. Good god. Yes, there are more economical vehicles with similar power and torque. But no V10.
I’ve read the info dump and read up on the engine (engine itself seems quite reliable). I’m just curious about all the little things - like the intake manifold, the PITA-to-reach-O2 sensors, etc. And does anyone bother with an aftermarket warranty in case SHTF? How much do you budget for unexpected repairs? All the basic maintenance - oil changes, brake jobs, etc. - I can do myself (or with the help of my mechanically skilled brother who is essentially an A4 master tech at this point with all the work he’s done). I might even be able to convince him to help me with a carbon cleaning 
A guy I know has a well-kept, 07 with 62k miles on it and would be selling it for a steal of a price that is all too tempting! I’m at the point in life where 4 doors makes more sense than 2, I’d be downsizing from a car and motorcycle to just 1 car, and owning this car would be just a freaking dream!
BTW - this place is by far the best resource I’ve found for info on S6s. Great work!
