Upgrading to the Cooper S Roadster will cost $3,000 more, while the John Cooper Works Roadster will run a cool $34,500 just to get in the door (plus destination and handling).
As with any MINI, the customization and upgrades are nearly limitless, but you'd best watch the bottom line: the MINI Yours Soda package adds $2,250 to the base Roadster's price, while the John Cooper Works appearance package costs another $2,000; the Premium package is available on all models and adds rain-sensing wipers, automatic climate control, anti-theft alarm, keyless entry and more for $1,750; and both the base and Cooper S models can add a $1,500 sport package.
There are literally dozens and dozens of other options--available in likely millions of possible combinations--that add $250 here and $750 there, including a $750 semi-automatic soft-top, chrome-line interior and exterior ($250 each), sport stripes (another $250), plus wheels, upholstery, and other options.
In other words, it's not nearly as hard to get a MINI Roadster over $40,000 as you'd think.
