The Infiniti FX arrived for the 2003 model year as a bold statement in the luxury crossover market. Built on Nissan's FM platform, which it shared with the 350Z and G35, the FX offered a rear-drive bias and athletic handling that set it apart. Its aggressive 'bionic cheetah' styling was polarizing but has aged into a distinctive look that many enthusiasts now seek out. The first generation (S50) ran until 2008, followed by the second generation (S51), which was renamed the QX70 for the 2014 model year.
Collectors are primarily drawn to the V8-powered models, the FX45 and later the FX50. These variants offer strong performance from their 4.5L and 5.0L engines, delivering a driving experience closer to a sports sedan than a typical SUV. The unique design, potent powertrains, and relative rarity of well-kept V8 examples make them compelling modern collectibles.
The market for the FX/QX70 is still quite affordable, with an average transaction price of just over $14,000. It's a vehicle that offers a significant amount of style and performance for the price. While high-mileage examples are inexpensive, the best low-mileage V8 models command the highest prices, showing a growing appreciation for these unique crossovers.
Buying Tips
- Check the dashboard on first-generation (2003-2008) models for bubbling or cracking, a common and expensive issue.
- The VQ35DE V6 engine can consume oil, so check the oil level and look for signs of blue smoke from the exhaust.
- Test all interior electronics, from the navigation screen to the power seats, as repairs can be complex and costly.
- Brakes on these heavy, powerful vehicles wear quickly. Inspect rotors and pads for wear and listen for any grinding noises.
- Listen for clunks from the suspension, especially on models with the sport package, as bushings and control arms can wear.
Prices range from $455 for project cars to $35,555 for well-preserved, low-mileage examples.
