Nah taks, it gets better than that. Since the fee is 180% of the amount you bought the car for in the first place, you'd have to pay $90k in registration for your $50k car, and then add the 25% tax of the total $140k, so in the end, you gotta pay $175000k... pretty horrible system, I know. But amazingly still people drive pretty neat cars.
That Infiniti looks awesome, by the way.
