Wait for the new A4, it looks very nice.
Mind you the way that Audi add things to the options list, can lead to a high total price. I was looking at a second hand S3 07 plate, no rain and light sensors, it was up for £27000 second hand

A few things were missing that are standard on the Golf:-
Interior light pack £140.
Rear centre armrest with cupholder
- with throughload (excludes ski bag) £125
Electric lumbar support £190
Light and rain sensor pack £190
