I honestly believe the 84 XE is the best Falcon/Fairmont Ford ever produced.
Alloy head X flow 4.1 Litre pushrod engine with electronic ignition (set and forget) and dual throat Weber carburettor (fit a fuel miser kit 5 yearly and forget).
Highway fuel consumption rate is about 11-12 L/100 Klm or 23-24 miles per gallon. I have always believed a little bit less in fuel economy is a small price to pay for ultimate reliability and longevity.
As taxis, provided they were correctly serviced and maintained, they would still be going strong after a million kilometres of use.
The ride and handleing are excellent with comfortable seating and very good all round vision.
The most common problems they have are water pumps and thermo housings corroding out and they usually need a new fuel pump and or alternator every 150 to 200,000 klms.
Sophistication in simplicity and poetry in motion.

This is an original 84 S Pac 4 slot manual I sold for $900 three years ago which I have been regretting ever since.
