The SL60 is a enlarged version of the 5.0L - its the older 5.0L, the 4 valve per cylinder one, they can only enlarge the 3valve one to 5.5 (which is why U now get a SL55)

The car was great, unlike the V12 SL600, the nose isnt too heavy, and it goes like stonk ;-)

My UK dealer took me out on a track day with most of the MB vehicles there (except the SLK (as that had just been released) at Goodwood.

I had a SL320 at the time, now I have a 3 year old SL500, I would have bought a SL60AMG, but I have a CLK55 for any moments of requiring extra acceleration !
