As hideous as I find the styling of the 3, the sales figures will be driven by the badge on the hood.
I drove an IS a couple of months back...with the manual tranny. It was nice enough, but didn't blow me away. Like many of the cars I've been looking at with 4 doors, the exhaust note is so muted...you can't hear much when you honk on it.
To get an IS with the manual & leather, I would have had to part with my 2-year old Protege5 and $30,000.
For that cash, I'd rather keep my car and:
(a) Get a used Porshe Boxster, or
(b) Get that beautiful 1987 Porsche 911 I saw with 38,000 km on it, or
(c) Get a used Cessna 152.
Needless to say, I still have my car...the Lexus dealer was "shocked" at my decision.
