I thought that the IS-F looked hideous when the first photographs of the blue one hit the net, but it's actually quite nice in black.
rrocket, who has tested the IS-F back-to-back with the C63? I've always thought that the IS-F was more closely matched to the C63 than the M3, though most reviews tend to compare the Merc to the BMW, then the Lexus to the BMW. I'd like to read a direct comparison between the Merc and the Lexus.
They weren't tested back-to-back, admittedly, but the C63 that C&D tested in its "$60k sport sedan" test was a half-second faster to 60 and a half-second faster through the quarter mile than the IS-F it tested in its "sedans that sizzle" test. That's not to say it's a better sport sedan overall...most reviews say that the IS-F is a sharp handler and the C63 is a bull in a china shop. And for the record, true to C&D form, the M3 won both tests.
