Nothing even compares to the 600s. I don't care what the 500 owners say about "oh the acceleration is the same, blah, blah, blah"... The 600s are in another league.Cheers! After two years, I still think that same thing every time I drive mine. I can't imagine what the M120 engine would be like.
Don't believe everything you read.Theres not many 600coupes in australia, I did'nt get to test 1, I tested 3 s500coupes and liked the Ride of the ADS suspened one with was better allround actually, so I bought that one, the power of the 600 would fun but going on what I've read over the years(sl r129 included) the 500s are the better handling car.
