The Lexus has more front and rear head room and shoulder room, more front leg room and more front hip room. The Mercedes coupe gives more leg and hip room to rear-seat passengers. The SC 300 has a better warranty and more horsepower. The CLK320 has more torque and gets better gas mileage. So, choosing between the two requires the scales of justice, the wisdom of Solomon and, perhaps, the flip of a coin.
Image is important, too, to coupe owners.
The Lexus has changed little in its years on the market. Luckily, for the car and its owners, it remains one of the classiest rides on the road. The look is both sporty and elegant, still contemporary without a bit of trendiness. The Mercedes has newness on its side. Out for just a few months, it's a car that turns heads and gets appreciative nods when people see it for the first time.
