One thing about this type of taxation is you see how much the UK and Turkey differ - in the UK until recently there were incentives to ditch your old (as in 10 year old plus) car and buying a new one. The Turkish system of course targets the gas guzzlers but the range is outrageous - from what, £6,000 per year to tax a Range Rover down to twenty quid for a year's tax on a smoky old antique. No wonder the roads are filled with dangerously ancient polluting old bangers.
