The chap I bought my spyder off sold a DB9 to buy it. He said the spyder was much more of a sports car and a better all round drive but it was too sporty for his wife. After he sold it to me, he bought a GranCab. It says quite a lot really!
As an aside, I used to drive quite a lot with a girl (Sarah) who has a de-catted (and pink wrapped) DBS and drives it like she stole it. On the straights and through the twisties, the spyder was never left wanting and I could always keep up quite nicely.
