Crappy interior, try installing an aftermarket Double Din headunit in there. :biggrin: No NAV option, GM's solution to this is some sort of turn-by-turn voice navigation with the dash indicator. It's like $100 a year AND you have to have OnStar service for it to work, however much that costs.
People will get bored of this soon. I remember when Ford first did the "retro" look on the Mustang... nobody gives them a second glance now.
