John,

I am fortunate to own both a SL and a SLK. I love both cars, the SL is my car for long trips, and the SLK is my drive it for fun car.

If I had to choose between then I would be hard pressed to decide, as they each have there own positives and negatives.

Your wife will most likely love the SLK.

Regards,
