NB Mk 2.5 trim levels

Hi there
Im keen to get another MX5 after selling my 2005 1.6 Icon last week.

I am keen to get an SVT because after a conversation with an MX5 guru i was told it was the one to get.
What is the differences between the Sport and the SVT, is it correct that in late MK2.5 guise there only was the SVT?
