Buyer’s notes
About the Jaguar XJ12 Series I
The XJ12 arrived in July 1972, putting Jaguar’s 5.3-litre V12 into the Series 1 XJ saloon with a simplified grille. Cooling it was a challenge, and Jaguar used a divided cross-flow radiator. A badge-engineered Daimler Double-Six followed, and the Series 1 ended in 1973, making these early V12 saloons a short run.
What moves the price
- Badge and body: Jaguar or Daimler Double-Six, standard or long wheelbase.
- Condition: these are big, complex cars, and rust or a tired V12 quickly costs more than the car.
- History: evidence the cooling system has been looked after.
Before you buy, check
- The cooling system in good order: an overheated V12 can drop a valve seat. Watch the temperature on a long test drive.
- The sills, wheel arches, doors, valances and floors for rust and filler.
- The independent rear suspension, its inboard rear brakes and the differential for leaks and worn bushes.
