Ferrari had great success with the California.
While not as fast as most of mid-engine Ferraris, it sold well. And its much better for daily use.
So what you think about a front engine Lambo?
Some would say this is going backwards, since they had a huge success with the mid engine Miura.
On the other side, compared to Ferrari, Lambos are about insanity, pretty much like Dodge Vipers, and Corvettes.
Now that I mentioned Vipers and Corvettes, Being more expensive, and exotic a front engine Lambo must completely outrun them and that might not be easy. It would need a 10 Liter+ V-12 or even a V16 to be able to do so.
