I recently traded in my BMW 328is for the Mercedes slk280. I looked into the BMW z4, Porsche boxster, and the Mercedes CLK in addition to the SLK. Besides some very minor interior design detail flaws the car is a perfect match. The dealership was a major factor in purchasing. Since BMW left me with a sour taste due to their poor customer service in the repair department. I chose the Mercedes which ranked in my opinion neck and neck with the z4. Mercedes service and responsiveness was out of this world. The entire transaction was effortless and w/o a doubt a fine deal all around. Absolutely no regret. SLK280 w/stand. Trans was more than powerful. The automatic version wasn't as fun.
Smart key and auto roof off. Concierge service.
The air scarf and better audio speakers should be standard. I settled for a model in dealer inventory and wished I had upgraded to air scarf package and better audio. You can't even upgrade to a 6 disk CD changer after market which was disappointing.
