Totally agree about the steering wheel and when you touch it is rather obvious that the leather isnt the same quality as the rest of the leather used in the car too - feels far less sumptious.  I think its a retrimmed part from the old ford parts bin myself. 

There are a couple of small things like that which all irritate you for the first few days (especially as I had just swapped out of 997 ownership) but they are soon forgotton when the whole aston ownership experience takes over.  Its a wonderful car and I still have no regrets.
