Some further thoughts
So was thinking about the brief encounter yesterday with the car, was waiting for a long time for a test drive so there was too much to take in during those 30-40 mins in total I got to drive it.
Firstly to answer some of the questions above if I may, there is no turbo noise as such. You get induction noise (esp in track mode where that system transfers the noise in the cabin) and then its exhaust/engine noises. So all in all think sth between an AMG type grunt (a bit more high pitch) and a ferrari screaming at 8k rpm. Very small turbo lag, also response is good, not very sudden. I would actually like even quicker throttle response as well as steering, but all that is personal preferance.
Second, yes the car is a daily driver, as it can be driven slow at crap roads. You can probably go shopping, go to long trips or.. to the theatre in this. No bad visibility, long nose to negotiate parking or u-turns, wide track for small roads etc etc.
And yes it handles better than a scud (an scud owner immediately told me this after his test drive) and it is waaaay faster. Also as he said, it is a hell of a lot easier at and beyond the limit, at a damp slippery airfield track with normal P Zeros (not R compount). But also more comfortable and less noisy.. With the scud you are forced to be in huper mode all the time, even at 30 kms/hr, here you get both. Pretty much what all journalists and mclaren marketing material have described.
So I was thinking about yesterday and was trying to find what i did not like. Well one has to admit that yesterday's drive conditions pretty much epitomised the usual downfalls of most sportscars. On crappy B roads at 40mph a performance car jitters, makes funny noises on pot holes etc, it just does not feel right. Also at the limit on a racetrack you almost ALWAYS get some (if not all) of the following; roll, squat under braking, braking fade, understeer, snap oversteer on exit under power, component fatigue etc. To be fair yesterday i did not get any of those.. And i am not comparing my observations to a standard 911tt or ferrari etc. I spend a lot of $$ and effort to improve the above on my car at the detriment of NVH/ noise/comfort and finally got to something that I liked. Well this car did it better to be honest.
And we did not get to drive it on the conditions that most other sports cars thrive on; highway with long corners, or mountain roads with smooth series of corners etc. Only tried it in the worst conditions that traditionally expose a car built for performance.
So why some people think that there is sth missing? Well after a long thought my opinion is that the answer is maybe somewhere in the above lines. Usually people are used to compromises; a 430 ferrari makes silly noises at a traffic light and jitters on crap roads but feels great on that perfect road. The 911tt feels better at slow driving and is much quicker and safe up to 8/10s but.. does not feel like a 599GTO or scud when you downshift or corner it on that perfect ride. The GT3RS is fantastic on that perfect road but is maybe too harsh on the bad roads, has a roll cage and that wing! (and imo lacks power and torque).
Here they tried to give it all at the same package. Its not italian, german or even a british kit car (see Noble or TVR). Its a combination I guess of what they liked in all of them without the theatrical performance of the ferrari and lambo - no the italian cars dont need to sound like they do when you drive slowly, or when you downshift. And no they dont have to transfer the engine vibrations in the cabin- these are all features designed on purpose to make you feel like a F1 driver when going slowly. They dont add performance or usability.
And that is maybe what confuses people?

I think the hopefully objective comparisons coming up on magasine reviews will be very interesting..
PS. I think i ll go with titanium silver (ceramics with orange calipers ) with most carbon options -except vanes- with a black/ carbon interior with orange stiching. You can get more exclusive effect with alcantara and some other dual colour combos, also the orange, black and red (especially) looked really nice imo but not for my intended use.
