Aw Yeah
 Sold the Cooper S and amped up from 194 hp to 255 on this 3.0si and we definitely appreciate the increased horsepower.  Initially test drove the 3.0 and were quite dissatisfied.  Same engine in the 3.0si as in the 07 335si and it shows.  Sports and Premium pkgs make this car all muscle and well worth going into a "Roadster" as opposed to a "Sedan" with muscle.  The one touch automatic ragtop is absolutely great because it truly is engineered right--tucks in snug and perfect.  What else would we expect from Bavaria?  Exterior is solid and didn't change in 2007 - so pricewise we scooped up a waiting 2006.  Great move.  Very glad we did.
