There is really only one Acura MDX model that comes with various options packages. As reported on The Auto Channel, these are the Technology Package, the Sports Package, the Entertainment and Tech Package, and the Sport and Entertainment Package. Which one you'll want depends on what your priorities are.
The reviewers at Edmunds.com were most impressed with the high-tech goodies available for this 2008 Acura. Even the base model (with no options) includes genuine leather seats as well as a sunroof, a fully adjustable steering wheel, XM Satellite Radio, and Bluetooth for hands-free cell phone operation. With the Sport and Entertainment package, owners can enjoy amenities such as an active damping suspension system for even greater comfort and control, as well as a voice-activated navigation system, real-time traffic reports, a 10-speaker audio system, and--for the kids on those long road trips--a rear-seat DVD system.
The only criticism here is not of the MDX Acura itself, but of manufacturer Honda; as usual, these options are not available on an a la carte basis--only in "package" form, according to Forbes Autos. As of this writing, the Technology Package runs $3,500, while the more comprehensive Sports Package is $5,600; adding the Entertainment option to either (it's not available by itself) will run you another $2,200.
