CGT is hard to beat.
Some options:
Murcielago LP640 - manual - overvalued in my opinion.
Diablo SV / SE30 - same. I would like GT
512M - looks cool, has some weak driveline issues
XJ220 - assuming you are passing on this since XJR15, but honorable mention - 6 cylinder is its biggest weakness
EB110
Saleen S7 twin turbo - kit car'y build quality, but has a hell of a presence
Not meeting all of your criteria:
997.2 GT3RS4.0 or GT2RS - supercar in the Porsche world, great chassis & driveline - I had 3rs. It was a great car but road presence was not even close to a ford gt
Murcielago SV - very special car, feels much different than LP640
360 CS - not quick, but inundated in sounds/feel
16M - add exhaust & headers for the highest of pitched exhaust notes
458 Speciale - the most responsive car, n/a, the only dual clutch that you can feel/hear
F40 - outta my price range
959 - same
Veyron - always thought it looked hideous.
