Though not a game breaker that would be good as cannot wait till MK8 R arrives (2017-18) so its this R or nothing as we stand (dismissed the S3 as would have to be a manual and no DCC and want both DSG & DCC)
S3 comes in manual and S-tronic, along with Audi magnetic ride (instead of DCC). The magnetic ride is part of the standard equipment on the saloon, which means it'll not lose you 80% of cost - as are 19" wheels (depends whether you like the S3 saloon, but apart from the colour (white - it would have to be Sepang blue for me) I loved the one at DTUK).
Admit to not realising that and my statement was from knowing have to spec nearly everything wanted when looking at A3 S line last time around - Still think the base price will likely be too rich for me and having seen a few A3 today am still as apathetic about them.
Will have a look at S3 at the time as going to see these cars is part of the fun but minds pretty set and as relaxed as ever been about car choice.
