Love driving my 250 after 17 months. Occasionally wish I had bought the 350, but I would rarely use the extra power. The 250 and 350 handle great on freeways, country roads or around town. The 250 is a little slow out of the blocks, but has great pulling power at higher speeds. I didn't buy the car with safety in mind, but this is one solid car. Someone crashed into the back of my car at high speed on a freeway yesterday, resulting in one totally written off car and one lightly damaged Lexus. At the time of impact I was pushed into a sideways skid, but handling was phenomenal and the car was brought under control easily.
Refinement. Comfort. Handling. Toys (satnav, bluetooth, etc.) plus AC seats in hot climates
Brake dust is easily ignored. For me the real issues are (a) rear legroom, and (b) lack of good cupholders! As these are the only issues that I have, it's safe to say this is a fantastic car that looks great.
