Lot details

Registration No: WUU 450S
Chassis No: 2R4951BW
MOT:
Exempt

  • 1 of just 1,200 or so fuel-injected XJ12 Series II cars made to RHD specification
  • Off the road and dry stored for the past quarter century
  • Credible 58,000 miles
  • Finished in Squadron Blue with Dark Blue leather upholstery
  • Notably solid and ripe for recommissioning

Introduced in 1972, the XJ12 was flagship of the contemporary Jaguar range. A four-door saloon blessed with Gran Turismo performance, its 5343cc SOHC V12 engine set new standards in production car design. A paragon of smoothness, refinement and quiet running, it was allied to automatic transmission and promised 140mph performance. Utilising the same advanced monocoque shell as its XJ6 sibling, the XJ12 also employed all round independent coil and wishbone suspension, four wheel disc brakes and rack and pinion steering. Heralded by the motoring press as one of the best cars in the world, it was reworked the following year as the Series II complete with a reprofiled radiator grille, more insulating bulkhead, superior electrics and improved heating / ventilation system. The shorter of the two wheelbases previously offered was dropped in 1974, while the following year saw fuel-injection adopted to the benfit of both outputs (285bhp / 294lbft) and emissions. A switch from Borg Warner Model 12 to GM Turbo Hydra-Matic 400 automatic transmission during 1977 led to even slicker changes. Just 1,200 or so of the 14,226 XJ12 Series II cars made were to right-hand drive, fuel-injected specification.

Issued with the distinctive London numberplate ‘WUU 450S’ on June 13th 1978, this decidedly rare, fuel-injected XJ12 Seres II is thought to have spent its life in and around the nation’s capital. Granted a tax disc by Marylebone post office during January 1983, the Jaguar had relocated to Waltham Cross six years later. Acquired by its current registered keeper in 1990, assorted bills show that the four-seater had attention paid to its GM THM400 automatic gearbox (shift kit, torque converter, mount), engine and suspension bushes plus a replacement sill that same decade. Dry stored for the past quarter century or so, ‘WUU 450S’ is understood to have passed its most recent MOT test on November 18th 2000 at an indicated 57,932 miles (circa twelve miles ago). Pleasingly retaining what is thought to be its original Dark Blue leather upholstery, the XJ12 appears to be substantially solid and complete. Treated to a new ignition set during 2019 and apparently in running order shortly thereafter, the Jaguar has since lain dormant and now requires thorough recommissioning / renovation. Cosmetically presentable ‘as is’ to our eyes, this Big Cat has the makings of a great project. Offered with V5C and paperwork file.
