As 2008 Infiniti FXs come very well equipped with standard amenities, the biggest decision is which engine to choose and whether it should power two or four wheels. The Infiniti FX (2008) can get pretty expensive if you go crazy with the options, though.
The 2008 Infiniti FX is offered in three models (no trims, per se): FX35, FX35 AWD, and FX45. J.D. Power details the Infiniti FX 2008's standard features: XM Satellite Radio, leather interior, a 300-watt Bose audio system with 11 speakers, 7-inch RearView monitor (that also functions as the radio and HVAC interface), 10-way power driver's seat, and an eight-way power front passenger's seat. "Dual-zone automatic climate control, Xenon headlamps, cruise control and split-fold rear seats are also found on all [Infiniti FX] models," they note.
Kelley Blue Book warns, "Some of the 2008 Infiniti FX's more attractive options are grouped into pricey packages and cannot be ordered separately." They helpfully indicate the Infiniti FX 2008 popular options as all-wheel drive (for the FX35), Intelligent Key, a moonroof, and a rear-seat DVD player. Kelley Blue Book details a couple of the 2008 Infiniti FX's packages. The "Technology Package includes DVD navigation, Lane Departure Warning and Intelligent Cruise Control [which] requires the Hands-Free package which includes Intelligent Key and Bluetooth." They also note that for those who "can live without navigation and a moonroof, the base FX35 is loaded with just about anything you might reasonably want or need."
