I had a 2008 1.8 TFSI A4 Sport, the sport spec sits between the SE and S Line, some nice extras on it like the Xenon's (a must for this model A4) and half leather interior, 3 spoke wheel etc, it was a fine car and good on petrol, 40ish mpg is doable. €570 tax and insurance was reasonable. I went from a GTi to this and didn't find it massively lacking in power. The only thing i didn't like about it was the clutch pedal was offset too far to the left, didn't make for the best seating position.
