The Jaguar XJ X350, introduced for 2003, represented a major technological step forward while retaining the model's iconic traditional styling. Its bonded and riveted aluminum monocoque chassis was a first for the brand, making the car significantly lighter than its steel-bodied predecessor and competitors. Power came from a range of V6 and V8 engines, with the supercharged 4.2L V8 in the XJR and Super V8 models offering impressive performance.
Collectors appreciate the X350/X356/X358 generation as the last XJ with classic quad headlights and a low-slung profile before the model's radical 2010 redesign. It offers a unique blend of old-world looks with modern mechanicals and a surprisingly athletic driving experience thanks to its low weight. The minor facelifts for 2006 (X356) and 2008 (X358) brought subtle styling and interior updates.
The market for these cars is broad, with an average sale price hovering just under $20,000 based on 217 sales. While high-mileage examples are very affordable, prices for pristine, low-mileage XJR and Super V8 Portfolio models can be much higher. The wide range shows that condition and specification are everything, with exceptional examples achieving prices that reflect their status as future classics.
Buying Tips
- Check the air suspension for any sagging at the corners after sitting, or for dashboard warnings; this is the most common and costly issue.
- Inspect the aluminum body panels for filiform corrosion, which appears as bubbling under the paint, especially around trim, badges, and wheel arches.
- Test all electronics thoroughly, from the central touch screen and navigation to the power seats and windows, as faults can be difficult to diagnose.
- Look for a complete service history, paying close attention to maintenance of the ZF 6-speed automatic transmission, which Jaguar claimed was 'sealed for life'.
- On V8 models, listen for any timing chain rattle on cold start-up and check for coolant leaks from aging plastic components.
Based on 217 recent sales, prices range from as little as $101 for project cars to a high of $175,000 for exceptional examples, with a market average of $19,230.
