Fun? The 2007 Lexus ES 350? A better word is pleasant. In routine driving, the vehicle is comfortable, controllable, easy to live with, and the potent V6 engine provides plenty of punch for an entry-level luxury family sedan. Fun, in car terms, usually involves some modicum of performance, either in regards to handling, power, suspension tuning, or responsive steering. Preferably all in abundance. Yet, except for the horses under the hood, the ES 350 doesn't dazzle in any of these areas.
