After driving a n sl550for 2 1/2 yrs. Its a lot roomier to say the least. After my test drive I knew I had to get one. The drive was awesome, takes corners like a champ, seating is very comfortable. The 268 hp engine is the same one that was in my slk 350 several yrs. Ago. Its quiet and has a lot of get up & go. Proforms well. I now can get several sets of golf clubs in the cargo area. I tested all the small suv's, this is definatly the best.
After having an slk, and sl model for the past 4 to 5 yrs I can honestly say I don't miss them one bit except for the convertible, oh well can't have everything. Best things are the handling, and the high in the air seating. I iike the burl dash a lot better than the chrome look.
They need to put in keyless go, I miss it. Breaks are spongy it concerns me.
