Jaguar XK Buyer's Guide
The XK8 and its successors are the standing rebuke to badge logic: 16 tracked sales at a median of £4,435 for a hand-somely styled, V8-engined Jaguar GT. The market prices these cars for their potential bills rather than their actual ability, which creates the opportunity and defines the risk in equal measure.
Know your generations
X100 XK8/XKR (1996–2005). Twelve sales, £2,000 to £15,510, median £3,798: the volume of this market. The supercharged XKR occupies the top of the range, and the gap between our £2,000 entry and £15,510 best is entirely condition and history; the cars were identical when new.
X150 (2006–14). Four sales, £4,251 to £7,313, median £5,685, remarkably low numbers for the aluminium-bodied successor and a sign this cohort was project-grade. Nationally, good X150s trade in the mid-teens upward, so treat our figures as the bottom of the market rather than the middle.
What to pay
£3,000 to £6,000 buys running X100s around the median, where the purchase is effectively a deposit against future maintenance. £8,000 to £16,000 buys the best X100s and honest X150s. Convertibles carry a premium over coupés throughout, and the XKR premium over the XK8 is smaller than the performance gap suggests, which makes the supercharged car the better value when the history supports it.
What goes wrong
On the X100: the well-documented early-engine pair (Nikasil bore linings on 1997–2000 cars, mostly resolved decades ago via replacement engines, and timing chain tensioners, which want the updated parts with invoices to prove it). Beyond those, sagging headlinings, corroded sills and floors on neglected cars, and electronics of the Ford-era Jaguar school. The X150 escapes the rust but adds aluminium repair costs when damaged. On both, a documented gearbox service history matters; the transmissions are robust when maintained and priced like exotica when not.
Our view
A £5,000 XK8 with tensioner invoices and a solid floor is the cheapest way into genuine grand touring that our entire dataset offers, and the styling has aged into elegance. Buy the best-documented car in the room, coupé for value or convertible for resale, and put £1,500 aside for the first year's discoveries. The X150 at our prices was a warning about condition; at national prices it is simply the same argument one generation newer.
