Here in Canada, it's slightly different.
Value Leader (Base Model):
3.7L V6 with 6-speed manual transmission
ABS with Traction Control
Electronic Power Assist Steering (EPAS)
17" painted aluminum wheels
Easy Fuel capless
Premium AM/FM/CD with audio input jack
For an extra 4000$(Can), you can get the Coupe Pony Package that includes all Value Leader features, plus:
Rear decklid spoiler
Unique Pony Grille and fender badges
18" Polished cast aluminum wheels w/Tri-bar centre cap
Power 6-way adjustable driver seat with power lumbar
You have to get the Coupe model if you want additionnal options like the Interior upgrade package that will set you back another 1700$.
You don't really get much for 4000$ more. I'm pretty sure that the Message Center is included in the base model as well since it's needed to program the "MyKey" thing.
Great powers comes with great responsablility.
