For the noise, it's just a slight vibration I can feel in the glutch pedal. No vibration - until today - when reaching the ends with the steering wheel.It only happens when I start up the car returning home from work (in that case, I do the maneouver described in my first post).
For the car, it is a "metallic gray ¿?" 156 Distinctive + pack sport. I was looking for a 147, but got the opportunity of an 156 at a lower price (It was a stock unit for sale after the renovation of the frontface last June, I think). Very beautiful, anyway.
I have no photos yet.
On the other hand this is my 2nd Italian vehicle at home, since I already own an Aprilia Falco (which has lost its battery due 1 1/2 moths driving only the new car ;-) ).
Thanks for your attention, guys.
