Welcome to the forume. I do have the 09 SLK 350 with the premium 1 package. It was about $3,000 to add it on and I don't think I could go without it now that I have it. I am not sure if you can get the Blue Tooth and Ipod without it though.
As far as a discount it is hard to say. In the Portland OR. area there are two dealerships owned by the same company so you realy can't play the dealers against each other.
You will love the car. It is a blast to drive for sure.
Sorry that I am no help with your questions |
