The Jaguar XJ6 established itself as the go to model for customers, elegant and refined but less heavy on the wallet and not as thirsty as the XJ12. The second evolution was more of the same with some updates to help with the series refinement. The series 2 used the straight six engine with improved fuel economy and the new heating and ventilation system was a great improvement as well.
The restyled front was a nice touch but was redesigned to conform to US safety regulations to help with international sales. The interior upgrade set the scene very nicely so the car continued on its successive run until the mid nineties with the release of The cutting edge XJ40.
The Jaguar XJ6 in series 2 & 3 form had very much become part of the British Leyland empire and with it came quality control issues and the Jaguar name had started to take a bit of a battering through the seventies and early eighties so give this car a thorough going over before making a decision to buy.
As you can imagine corrosion is a problem for many British cars of this era so check all the areas below: inner and outer sills, front wings, lower bottom edge and round the headlamps, inner wings, battery tray, rear valance, rear wings and boot lid lower edge. Also check the spare wheel well (under the carpet) screen surround and door bottoms.
Mechanical the cars are complex, you will need to ensure good history with an XJ6 as they are good runners even when in need of TLC as the engines are very smooth and easily disguise any problems. Coolant quality is vital to the engines long life, listen to the car start up from cold, any knocks or bangs may be worrying also check oil pressure which should be around 40 psi at 3000 rpm when warm. Gear box should work well if a little unresponsive.
The independent rear suspension and sub-frame is a complex affair with rear brake discs mounted inboard just to add to the complications. Check for any perished rubber mountings or joints. Propshaft, half shaft or even radius arm mounting problems can be detected by a clunk when selecting drive. Have a good luck at the tyres, if any noticeable wearing is on the tyre shoulders this could be a sign of problems with suspension area front and rear.
Interiors are hard wearing but big Jags can mean lots of miles which adds to wear and tear inside the cabin so check for sagging headlining as the only cure for this is a replacement. Join a club they can help with finding trim for your Jag instead of slogging round the autojumble’s although some may enjoy this.
Jaguar climate tests all its vehicles in a freezer at -40 degree Fahrenheit for 12 hours. Then they stick the cars into a wind tunnel with air streams that are 0 degrees all while spraying the car with water. This is to ensure that, no matter how cold it gets outside, your Jaguar will run like a dream.
Mark Wilkinson, Managing Director Says:
“The Jaguar XJ6 like all good Jaguars was continually being developed and updated through each series which in turn ensured production of these amazing machines never stood still, giving the customer the best Jaguar had to offer.”
