My SL55 is a MY 2006 (according to spec check-( 806 - YEAR OF MODIFICATION)) and it has the wider rectangular shaped command screen when compared with the earlier models smaller and squarer version. I therefore assumed that my SL was the "2006 facelift" model that were showing up from Late 2004 onwards...However, my car only has a 5 speed transmission. , I recently read that facelift cars have a 7 speed box. So, I am confused, is mine some kind of facelift version or the same as the earliest year models but with a freak command system upgrade? PS. My car has 4 slats in the front grill which I would also associate with pre-facelift cars. I did try and research online but couldn't find a definitive answer Thanks if you can help clarify this for me.
