They're very nice, very well made cars, but they're the dullest looking lineup of any luxury car brand hands down. Not even the SC430 inspires any lust. I'll take a IS350 though, had a lot of fun driving it at the Taste of Lexus last year!

The SC430 is almost good looking from this angle, it doesn't reveal the bathtub look as bad in this shot.
