The Jaguar XK150, produced from 1957 to 1961, was the final and most refined model in the XK series. It introduced significant updates over the XK140, including a one-piece curved windscreen, a wider body, and standard Dunlop four-wheel disc brakes. Power came from a 3.4-liter inline-6, with a more powerful 3.8-liter engine and a high-performance 'S' model with 265 hp arriving later. Body styles included the Fixed Head Coupé (FHC), Drophead Coupé (DHC), and the spartan Open Two-Seater (OTS) roadster.
Collectors appreciate the XK150 for its combination of iconic 1950s styling and improved drivability. The disc brakes, in particular, make it a much more usable classic than its drum-braked predecessors. The high-performance 3.8 S models are the most sought-after variants, especially in the rare OTS configuration. It represents the pinnacle of Jaguar's first post-war sports car family before the E-Type's arrival.
The market for the XK150 is well-established, with an average price of around $72,000 based on 68 recent sales. This price point covers a wide spectrum of cars, from accessible driver-quality examples to fully restored show cars. The top of the market, exceeding $200,000, is reserved for pristine, numbers-matching 'S' models and rare body styles.
Buying Tips
- Rust is the primary concern. Thoroughly inspect the sills, floor pans, chassis outriggers, and the area around the headlamps and rear wings for corrosion and poor repairs.
- The XK engine is robust, but check for low oil pressure when warm (should hold 40 psi), evidence of overheating, and listen for rattling timing chains on startup.
- Verify originality. Matching-numbers cars carry a significant premium, so check the chassis, engine, and body numbers against a Jaguar Daimler Heritage Trust certificate.
- The Dunlop disc brakes can be costly to service. Check for seized calipers and warped discs, as parts and specialized labor can be expensive.
- The DHC's convertible top mechanism is complex. Ensure it operates smoothly and the fabric is in good condition, as a full replacement is a multi-thousand dollar job.
