Chevrolet has decided not to muck with the successful formula, with the only changes for 2010 consisting of an optional rearview camera and the elimination of the sporty SS trim for the HHR Panel body style.
Standard features include air conditioning, an AM/FM/MP3/CD sound system with auxiliary input jack and satellite radio, power windows/locks/mirrors, remote keyless entry, cruise control, 16-inch wheel covers, a trip computer, and the aforementioned OnStar system.
ConsumerGuide reports that the vehicle's "features availability are competitive" in this segment and price range.
Kelley Blue Book states that one of their favorite features is the "front-mounted auxiliary input jack [that] makes it easy to connect any MP3 player or other audio source to the HHR's sound system." Optional extras include “leather seating, heated front seats, power driver's seat, stiffer suspension, power moonroof, 260-watt sound system with subwoofer, in-dash six-disc changer, MP3 compatibility [and] XM Satellite Radio," they say.
Edmunds points out that "major options for the LT include remote vehicle starting (included with the 2010 Chevrolet HHR automatic transmission), leather seating with heated front seats, in-dash CD changer, satellite radio and a sunroof."
