As some of you might remember, I began my SLK search a few short months ago. I decided on the 350 SLK, however I've not finalized the deal...I'm waiting on the first SLK that comes into my area (Florida) that is the right price along with the right color. I'm looking at years from '06-'08 and wont settle until the right one comes in with the right price. Thus far, they've been cycling through 2-3 every week. Before I end up buying though, I was curious, do the '06's come with a nav? The reason I ask this is because I was under the impression that some did, however I have yet to see one with it. Just curious...thanks friends!
