Yesterday I was lucky enough to get to drive a series 2 997 GT3 RS from Melbourne to horsham. while not the twistiest road in the world, it was still an enjoyable drive. the racing seats were extremely comfortable, and sat as a passenger for most of the way to Adelaide (about 600kms in total) and didn't have a sore back at all,
the gearbox was very stiff but had a good solid feeling, clutch was much the same, you would end up with an oversized left side of your body driving this car every day. that said, it was extremely smooth and quite easy to drive slowly through towns and take over speed humps.
engine noise was good, and on big acceleration you could hear the exhaust note change (im assuming it has valves) but still not overly loud (comparing with 458/gallardo). road noise was pretty bad though depending on the road surface.
only issue i had with the car was keeping it straight with the wide tyres and the ruts in the road, with more camber up front than standard, it wanted to wander around on the road, but this is obviously set up more for the track, so no big deal
Ive never been a huge fan of porsches, and although the turbos are fast, they have never really excited me, but the RS ticks all the boxes for me, and i would buy one if i could! the engine response felt more like the 458 italia and to some extent a gallardo, maybe not quite the kick in the pants the gallardo gives. but in 5th or 6th, had more than enough power to overtake a car in very little time. and more than more than enough power to overtake back in 3rd
