New Buyer: 07 vs. 08 Commander Changes

We are ready to buy a Commander and have test drove the '08 model. I have just been offered a '07 w/the 4.7L, roofs, 13K miles for about $17.5K ... which I will be driving tomorrow.

Differences seem to be more HP in '08 and a more refined dash and steering wheel.

What else am I missing?
What are owners experiences with the HP difference?
Recommendations are appreciated as well.

Basically is an '08 worth about $2K more for same equipment. Please educate me as we plan to purchase soon. Thanks in advance.

For the 2K, how much more warranty will you receive and the peace of mind that comes with it?

There is no difference between the '07 and '08 engines--no changes were made. There IS an increase in horsepower for the '09 models.

That's not entirely true, it depends on the engine. The 4.7 in the '08+ is a different model from the 06-07 models: more hp & torque, 16 plugs, different air intake, etc.

Sorry, bud, but you are wrong on that.

You didn't mention how many miles are on the 08, but 13,000 miles on an 07 seems like low miles. So at least it has a lot of life left. I assume you are saying the 2 vehicles are equiped with the same options. If not, add them to your calculations. Other than that, it would seem that there are few differences from the 07 to the 08, except for the warranty that 49er mentioned in his post.

There is a difference in the '08. 300HP and 340 torque. They altered the existing engine and fine tuned it. there is also a difference in the '08 Hemi, more power, more fuel economy.

We now have more exclusive details on additional features that will be offered on the 2008 Commander models:

Hill Ascent control assists the driver when starting a vehicle from a stop on a hill by maintaining the same level of brake pressure the driver applied for a short period of time after the foot has been removed from the brake pedal. The system will release the brake pedal in proportion to the amount of throttle applied. If the throttle is not applied within a short period of time after the foot has been removed from the brake pedal, Hill Ascent Control will release brake pressure.

Hill Descent control allows a smooth and controlled hill descent on rough or slippery terrain without the driver needing to touch the brake pedal. This system applies the brakes to each wheel individually when needed to reduce forward motion while negotiating down steep grades.

Trailer Sway Control is another new feature that will be offered on vehicles equipped with trailer tow packages. Trailer Sway Control reduces trailer sway (an alternating yaw of the vehicle) and improves handling in adverse towing conditions caused by crosswinds and traffic, provides trailer stability and increases towing safety. The system monitors the vehicle’s movement relative to the driver’s intended path, and the vehicle yaw sensor recognizes sway. Trailer Sway Control applies brake pressure on one front wheel to counteract the yaw induced by the trailer and applies brake pressure to all four wheels to slow the vehicle. As the trailer sways to the other side of the vehicle, Trailer Sway Control will increase pressure to the opposite side of the vehicle. The system will continue to apply alternating brake pressure and reduce engine torque until the trailer is under control.

Engines: A new 305-hp version of the 4.7L engine is set to debut in the Commander for 2008. The 3.7L and 5.7L Hemi engines will continue to be offered.

Other expected changes for 2008, the 3rd year of the XK generation, may include some interior upgrades and as well as some minor exterior changes.

He was referring to the 16 plugs reference. I don't believe the new 4.7L has bumped up to 16 plugs. Only the Hemi uses 16.
