Just crunched the numbers for my specs of the cars I'm considering. Here's the out-the-door costs with tax, title, registration and everything included:
$65,150 - 2013 Boxster
$58,250 - 2013 135is Convertible
$55,500 - 2013 135i Convertible
$46,800 - 2013 MINI JCW Roadster
So there's a $6,900 premium for the Boxster over the 135is Convertible.
And there's a $8,700 premium for the 135i Convertible over the MINI JCW Roadster.
And there's $2,750 between the 135is and 135i.
