^ You're right, I forgot about the GT1.
I haven't driven either and probably never will, but part of me thinks that the SLR is probably more comfortable and easier to drive than the LF-A.
The difference between the Enzo and the LF-A is that the Enzo was the next in line as their limited production hypercar released during each decade, offering performance on-par, if not class-leading, during its release. You could apply this to the Carrera GT (which I should've mentioned instead of incorrectly saying that it was their first hypercar, which is still arguable since the GT1 was produced in such limited numbers just to meet the GT1 race category regulations) but not necessarily the LF-A. Granted 0-60 mph acceleration times aren't the end-all of measuring a car's worth, but it IS probably the EASIEST performance measurement to meet (if not exceed), yet it still trails behind by a few ticks. I'd think it should at least be AS quick as anything else within reason at that price range.
