Anyone went from E90 to A4 B7 (or vice versa)?
Does anyone here have experience running both B7 A4 Quattro and E90/E91 (not necessarily at same time of course)?
My main question is - how they compare on reliability and running costs (especially audi vs NA engine bmw).
If you've run both, you probably can compare the main weaknesses and how much it takes to put them right... So as a used ownership I'm looking for some feedback on the A4 B7 versus the bimmer.
I've driven the A4 so I'm aware of handling, interior, ergonomics etc so that much is clear.
