I can some-what understand the purpose of it on a new, dealer-purchased car: to channel taxes back from the purchase of a brand new vehicle. But why on used cars, do we have to pay a tax based on a percentage of purchase cost? The sale of used cars does nothing for our GDP, whether it be a $1200 car, or a $120,000 car. The stamp duty should be a fixed charge regardless of the purchase price of the car, and a reasonable amount; not $4,000! I don't understand the purpose of it, especially since we already have to pay out of our ass for registration as it is!
LOL, so did I. It was a sad day.
