I've owned an A3, have an A4, a Passat, Jettas and Golfs. I'd bite the bullet and get a Golf R simply for the value holding aspect.
For a better deal get a couple year old A4. The longitudinal 2.0 and DSG is the best engine/transmission combo I've ever driven and the back seat is way better than the A3
