Hiya i agree with Koala ,we too loked into bringing the car but with all the taxes you pay it just isnt worth it ,we bought a 8mth old car at a reasonable price from a dealer ,,remember its normal to haggle. Tax and insurance isnt like the uk ,each vehicle has a rego ,which includes basic 3 rd party insurance,you pay 6mth,or 12mth but i cant remember off the top of my head how much it was ,i think around $600
pr yr.There isnt an mot either although when buying a 2nd hand car it should have a Roadworthy Certificate,hope this helps a bit
