He bought them on-line at
http://www.sewellparts.com. They were $299 with tax and shipping to your address.
I love the car. I came out of two cars, a Mercedes CLS500 and the Infiniti G35 coupe. Sold the Benze because I wasn't driving it much and sold the G because I needed more room and was tired of sitting low to the ground.
The FX is sweet. Ride a million times smoother. All the tech gadgets I could ever need (except actual Tech package as I didn't need that much crap).
Overall, it is a very luxury ride, very comfortable. The only thing is the 7 speed trans takes some getting use to but I don't have some of the hard shifts and gear searching other have had. When slowing to a stop it will jerk a bit but onlu on occasion and not all the time. Also, I know it has 303 HP but the G was much quicker and faster but then again the FX is larger and probably a lot heavier so that also takes some getting use to.
I don't regret the purchase at all. Build quality is great. Fit and finish is tight with no road noise, rattles, etc. Infiniti keeps getting better in my opinion, which is why there will always be one in my garage.
Enjoy the FX. Let me/us know how you like yours.
