I'm not to worried on teh repair on the plug in part. My dad owns a Diesel F-350 that we plug in anyway, not to much of a pain. One of our tenants is a mechanic and does all the work(rather, tells me how to do it) on all of our vehicles(unless their under warranty of course).
The gas mileage thing was my main qualm with the A4, becuase on fueleconomy.gov is said it only gets upto around 25mpgs, which while not bad isnt amazing. But if it can break 30mpg, i'd be happy. I generally baby my vehicles in normal driving. Hell, I never even knew my truck had a shift light, I was just going by sound(no tach). And it was getting 15mpg on a good day. I'm scared to see what it'd get if I romped on it.
EDIT: Yes, A4's are sexy, why do you think i want one
