on the issue of driveability, it is 100% accurate to say the car is very driveable still, very close to stock, so no worries with the wife driving your car! the only time you dont get boost on the car is at a cold startup (when the engine warms up and you have the warm up gauges). there is no ON/OFF boost on the blower, LOL, maybe you need to invent one. ...

gas mileage is bad. dont hope for anything close to stock. i think you get 11-13mpg now....right foot or not! at the height of the gas $$$ i bought a 2nd car so the x5 wouldnt put a hole in my wallet every month on gas bills...

S3 4.6is are very few made, so you will get your exclusivity. 46k sounds like a deal to me for that car with that mileage. make sure all the dinan parts are intact and that there is no a/c leak (that was my problem). the whining of the supercharger is whats music to your ears when you drive this car...hope you get it!!!!!
