a few of my friends have xf falcons, ones got a 4-speed manual 6cyl, the other with a 5-speed, and another with an auto (a fairmont) which ive driven, good car to cruise really light in the steering but it had a few problems, the kick down switch didnt work and alot of oil leaks, the only thing i didnt like was the poor turning circle. another mate of mine has a TE cortina with a rebuilt 6, 4-speed manual and a mini spool. i raced it off the lights and it beat my AU up until 80km/h, i couldnt believe it.
