I've had my 2009 Granturismo 4.7S for just over a year now and have finally decided that the totally annoying creaking sound from inside the car is coming from the drivers seat. Amazing how tricky it is actually trying to pin down where the sound has been coming from. I was convinced it was from the steering wheel area (possibly leather dash trim rubbing?) and I think I even posted about that. However, concerted effort today on a rare longer drive to pin this down. Definitely drivers seat. It creaks pretty much over every bump. I'm clearly totally overweight but I think a 6 foot tall, 14 stone bod is not too much weight for the seat . I think it must be the springs in the seat. Anyone experienced this? If so, any quick fix ideas or is it a bigger job/cost?
