I have just sold my R32 DSG (my ad was here with pics http://www.eastwestracing.co.uk/html/r32_ad.html
) i have only had my S3 2 wks and now I am in Iraq, so will not be driving it until June!! I wrote a review http://www.audi-sport.net/vb/showthread.php?t=47075
and made a few comparisons against my R32 in it.
they are both very different cars. The R32 sounded wonderful, it was smooth, which gave the impression it was not lighting fast! DSg is a must and was beutiful in heavy traffic and the paddles always caught the eye.
It did however rattle alot, had problem with brakes and steering was awful, all problems associated with the r32.
The S3, well altogether very well put together! very well made, feels very tight and ooses quality and prestige. Ride is firmer than R32, but seats are more comfortable (i had recaros in r32)
Feels so much more livelier and lovely whistle from turbo. Does however sound like a diesel on tick over! steering is superb, very light, if too light, but better than r32.
looks are very understated, could easily be mistaken for an s-line to the untrained eye.
If i had to choose, it would be hard. i like qualities form both cars and to be honest have not had the S3 long enough to make a proper asumption.
Try each of them out.
