From Auto Express Issue 635:

Audi has cut the price of its A3 by 4.5 per cent. Prices now start at £14,605 for the entry level three-door 1.6, rising to £21,515 for the five-door 1.8T Quattro.

No mention of the S3 though!

I checked with Audi and they confirmed that the S3 price is NOT being reduced.

The new A4 3 litre quattro is just under £25000 !! It makes you wonder what the others will end up costing or more to the point ours will be worth.
