Key strengths: Better fuel economy, smooth power
Areas for improvement: Oil leaks, A/C
Comparing th 3.6 AUTO to several V12s I have owned I have to say that fuel economy on a daily basis has improved by 25%+. This makes it useable as an everyday XJS. It pulls well and is smooth/quiet.
Go for a later ZF 4 speed auto with cruise control.
Personally I find the sports pack suspension a little choppy compared to standard. I am looking to go for a new set of standard spec dampers (shock absorbers)
Make no mistake the 5.3V12 is still one of the smoothest power engines around even after 30 years of production.
In summary an XJS is still a modern classic which can be used everyday. It puts a smile on my face each morning I get into it for work. Looks so right.
Maintain them on the regular basis and they will reward you...
Hopefully you will already know how good an XJS is for comfort, ride quality and driving pleasure.
Problems have been confined to a leaking oil cooler/pipe joint and a blocked air conditioning valve which was replaced on a re gas / new receiver dryer.
The running costs for Jaguar XJS 3.6 Automatic are normal
