Talking of taxis, why do you think all the taxis are Ford Falcons not Holden Commodores? Falcons are much more reliable. I recently got rid of a DR30 and am now in a 2004 BA Falcon. Couldn't be happier with my choice as the car is 22 years newer, has a new car warranty and all modern interior gadgetry. The 4L engine displaces 182kw standard and even though it is powering a 1600kg car, it has more than enough poke.
I could have bought a R33 GTST or a well used R32 GTR for the same money, but you can only do the speed limit.
