My Mom drives the SLK350 with the premium pkg and sport pkgs, and neck scarf (totally cool!) she has a mars red on black leather, she and I totally love it! It in my opinion is twice the car at least as the 3.0i Z4 (I had a 2005 SMG 3.0i with every option sans m sport seats) and I did not like the Z4, it feels cheap, way overpriced and is full of rattles, its in my opinion way overpriced and while not as cheaply made as the *grimmaces* X3 its just no X5 haha, so my opinion? The SLK350 is an amazing car, very expensive but worth it if you can afford it
