For Sale: 1959 Jaguar XK150 in Saint Louis, Missouri

Few postwar sports cars embody the elegance and mechanical sophistication of Jaguar's legendary XK series quite like the XK150. Introduced in 1957 as the final evolution of the celebrated XK line, the XK150 represented the most refined and capable development of the formula first established by the XK120 nearly a decade earlier. While retaining the unmistakable long bonnet and graceful curves that defined the series, the XK150 incorporated numerous improvements including a wider body, a modern one-piece curved windshield, improved interior comfort, and powerful four-wheel disc brakes-still a relative novelty in production automobiles at the time.
Beneath the bonnet resides Jaguar's famed twin overhead-cam inline six-cylinder engine, one of the most celebrated powerplants of the era. In standard 3.4-liter form, the XK150 offered strong, flexible performance paired with exceptional smoothness, making it equally at home on twisting country roads or long-distance grand touring. Combined with Jaguar's well-developed chassis and precise steering, the XK150 delivered a driving experience that balanced sporting character with surprising comfort.
The example offered here, chassis S 837996, was originally completed on December 29, 1958. According to available records, the car was delivered new to its first owner in Mill Valley, California, where it began life in an elegant specification of cream over a red interior with a black canvas top.
In 2007 the Jaguar was acquired from Hyman Ltd. by a subsequent owner who embarked on a comprehensive restoration with the goal of returning the car to like-new cosmetic and mechanical condition while subtly improving drivability. The work was carried out by respected specialists, including a full engine rebuild by Bill Terry, with a detailed file of receipts documenting the process.
As part of the restoration, the car was refinished in a Cotswold Blue over a beautifully trimmed tan leather interior, complemented by a tan canvas convertible top. The result of the restoration is a charming XK150, with deep, lustrous paintwork that highlights the flowing lines of the XK150's body. Chrome and brightwork are beautifully presented, while the car rolls on chrome wire wheels secured with knock-off hubs, completing the classic Jaguar sporting appearance.
Under bonnet detailing is excellent, and the car features a period-correct 3.4-litre XK150 engine paired with a Tremec five-speed manual transmission. This thoughtful upgrade dramatically enhances the driving experience, providing smoother shifting and more relaxed cruising capability while maintaining the character of Jaguar's legendary inline six. A 3.54:1 rear axle ratio further contributes to the car's excellent road manners. Lastly, a tool roll, jack, and knock-off hammer accompany the car.
The result is a Jaguar that performs as beautifully as it presents. The engine starts readily, settles into a smooth idle, and delivers strong, responsive power. On the road, the XK150 feels composed and capable, making it an ideal companion for touring events, spirited weekend drives, or relaxed open-air motoring.
With its balance of sharp handling, gutsy power, and vastly improved passenger comfort, the 150 is the driving enthusiast's pick of the XK range. Featuring great colors and thoughtfully upgraded driveline, it offers the rare combination of visual elegance, engaging performance, and modern usability that makes the XK150 such a rewarding classic to own and drive.
