Well covid did for a trip to Australia so the slk went in px for the E class instead. I have studied the manual but there are so many things to get used to. It drives very nicely and does mid 40's to a gallon, very comfortable and easy to see out of which wasn't the case with the slk. Had a major service from the main dealers before I got it but after the warranty year runs out it will my trusted indie looking after it.
