The X350 generation Jaguar XJR, launched for 2004, marked a technological leap with its advanced aluminum monocoque chassis. This construction made it significantly lighter than its German rivals and its steel-bodied X308 predecessor. Power came from a supercharged 4.2L AJ-V8 producing 390 hp, providing formidable performance that was often compared to the BMW M5 and Mercedes-Benz E55 AMG of the era.
For the 2007 model year, a facelift introduced the X358 designation, bringing revised front and rear bumpers, a more prominent grille, and front fender vents. The engine's output was also bumped to 400 hp. Collectors value the X350/X358 platform as the last of the traditionally styled XJ models, appreciating its blend of classic lines, modern performance, and luxurious appointments. The supercharged V8 and lightweight body create a driving experience that's both elegant and aggressive.
The market for these XJRs represents a significant performance bargain, with an average sale price under $15,000. While early, higher-mileage cars can be found for less than $10,000, exceptional, low-mileage X358 examples are now commanding prices over $30,000. These cars offer a tremendous amount of speed and luxury for the money, but deferred maintenance can quickly erase any initial savings.
Buying Tips
- Check the air suspension for any sagging corners, which indicates leaks in the air springs or lines. Listen for a constantly running compressor, a sign it's working overtime to compensate for a leak.
- Inspect the aluminum body panels for bubbling or corrosion, particularly around the wheel arches, trunk lid, and window trim. Aluminum doesn't rust, but it can suffer from galvanic corrosion and filiform corrosion under the paint.
- The 4.2L V8 is strong, but listen for rattling from the timing chain on startup. Also, check for coolant leaks from the plastic thermostat housing and aging hoses, as overheating can be catastrophic.
- Scrutinize the service history. Regular maintenance is key, and records for replacements of common wear items like suspension components, transmission fluid, and supercharger belts are highly desirable.
- Test all interior electronics, including the touchscreen, climate controls, and power seats. Electrical issues can be time-consuming and expensive to diagnose and fix.
Prices for the Jaguar XJR range from around $4,700 for project cars to over $35,000 for top-condition, low-mileage examples.
