I got a chance to drive a GLK350 last year at the auto show in TO, it was a blast! The thing that struck me most was the turning radius, it's better than my compact car, and made even the E350 they had on the course feel like the Bismark. Acceleration was strong and the engine note was aggressive. The meaty steering inspired confidence in the corners, as did the competent suspension. But as I pulled up to a stop and parked, I noticed how refined and quiet it was - the GLK really has two personalities, which makes driving more fun. I don't feel the B200 is vying for the same market. It's the Baby Benz, aimed at keeping the price low more than prestigious transportation. The B200 felt as though it was going to tip over at any minute, the dynamic limits of the vehicle were much lower when compared to the athletic nature of the GLK. If I was merely looking to get room out of a small package I'd skip the B-class and buy a Honda Fit!
