They didnt build any 4wd models with a naturally aspirated 1.8 engine, at least not in the UK.
quattro was an option on either 2.6/2.8 v6 models, late 1.8TQS, and 1.9tdi or 2.5tdi.
Seriously, a 1.8NA A4 is going to be ****. Get a turbo car. They're not fast, but they're MUCH nicer to drive than the 1.8NA.
