Back when the 1997 Q came out, with the 4.1L, I thought that Infiniti had lost its mind! The car I thought then that they needed to make (and still do!) should be the:
Infiniti Z60
With a 6.0L V-12, 375+ HP, tons of torque, five-speed auto, luxury galore, to compete head-on with the big Benzes and beat them hollow! (Given the new 3.5L engine, they ought to strap two together and make it a 7.0L V-12!)
I once wrote up a long letter to the Infiniti USA President to expound on the virtues of the above car, but never mailed it.
