DX, LX, EX, and Si versions of the Honda Civic (along with GX) cover all the bases. You can get what you want on the 2010 Honda Civic—even leather seats—provided you’re willing to step up to the more expensive trims and pay quite a bit more.
The base 2010 Honda Civic DX is pretty basic, with no air conditioning, but power windows and door locks and a tilt/telescoping steering wheel are standard on all models. The Civic LX has air conditioning, cruise control, power locks, a CD audio system with an auxiliary jack, and a folding rear seat. The EX sedan gets distinct alloy wheels, a sunroof, and an available navigation system with XM Satellite Radio. And although a leather-upholstered Civic seems a little odd, you can get exactly that, plus heated seats and mirrors, in the Civic EX-L edition.
Car and Driver notes that "the Si model is essentially outfitted the same as an EX," and the Honda Civic "GX is equivalent to the LX trim level."
Last year Honda significantly revamped the Civic’s feature list to make widely desired tech features more available throughout the lineup. Bluetooth HandsFreeLink and a USB audio interface, along with satellite radio and a nav system, are now offered—though in typical Honda fashion, you’ll need to step up to the most expensive EX versions to get all of it. The nav system in particular is a feature you won’t find on most other affordable vehicles in this class.
The navigation system "includes voice recognition and steering wheel-mounted controls," according to Cars.com.
