I've got a white 1988 EA Falcon on gas. Runs well on petrol and gas and is cheap as to run (500km to $35 of gas). Since august it's had a reco head, new radiator, new water pump and thermostat, new gas converter, new front pads/discs and rear pads, new front upper control arm bushes. Probably other stuff that i've forgotten too! Would need the gas tank re-testing and a set of springs for roadworthy but that's about all.
Looking for $1000 as is or $1500 with 12 months rego.
