Just 35,000 Saturn Skys were made for the 2007 through 2010 model years. The single-generation two-seat roadster is on many car enthusiasts’ radar as a future classic, so you’d do well to hang onto yours.

The standard Saturn Sky is powered by a less-than-thrilling 177-horsepower, naturally aspirated inline-four-cylinder engine. Redline versions benefited from a more powerful 260-horsepower, 2.0-liter turbo-four engine. And from December 2008 onward, buyers had the option to add a turbo upgrade kit that piled 30 horses onto the Sky’s stable and pushed torque from 260 lb-ft up to 340.
