I see, thanks for the info. I wonder how old a used car with a bigger engine would have to be for the taxes to be similar to that of a new car with a small engine. It makes me curious if cars with bigger engines that are 2-5 years old would potentially be more popular to buy than a brand new car with a smaller engine.
