I am in my second month of V10 ownership having come from a B6 4.2 V8 S4 and I would say that so far (aside from a slight condensation issue) its been rock solid, not had any problems or lights, clean VCDS scan the other day - i've done just over 2,000 miles and average 19.4mpg across all driving styles during that time (tracked MPG not lying trip computer mpg)
Fuel wise, the tank is bigger than my S4 and swallows £90 a time at BP or Shell, but I was averaging 22mpg or so in the S4 so the difference between the two isn't that bad.
Essentials: B&O, full history, steel brakes
Insurance is cheap at £430 for the year fully comp, protected NCB
I wanted black or grey, really didn't want silver or blue, ended up with silver and glad I did, so don't be put off by the colour, go for the spec and the history first
