Since the A4 has 80k miles its due for a TB change and thats going to cost $1500+ right off the bat.
You would have more fun driving the A4 over the Passatt since You are moving from a VR6.
The 2.0T unless its had some serious wor done is going to seem like 2.SLOW.
Cost of maintenace is high on the Audi.
