Mats were standard in the RS always and they are RS ones. It was the cargo netting that was missing, and from memory only in the sedan, the wagon in both guises had it from memory. The Elegance also had full leather with electric seats, late in life the Mk2.5 got full leather but never the electrics. I had enough Europcar Elegances and Ambients hired that I should have "borrowed" one of the never opened packets of nets that clearly kicked around in the boot for years. The RS had the bigger engine with manual option (was the only option originally), lowered sports suspension, the 18" wheels, the alarm (although that went and returned at times), the special seats, sports steering wheel (although no controls until the DSG arrived), rear parking sensors (front available), the spoiler and different front bumper, tyre pressure monitoring and from memory the dark interior was different and not available for the Elegance. Probably a few bits and bobs I missed.
The Elegance this time around seems to come with more stuff so will be interesting what the RS comes with. I think the guessed price of a 6MT hatch is about right, ie 38k driveaway, a bit more with a tech pack. Still seems as if the RS will be missing those extra airbags which is odd, unless they come as a tech pack addition. They may end up much the same, but geared towards different markets, the RS will be stiffer and lower and "sporty" whereas the Elegance is like the 147 TSI Jetta with a more refined setup.
