TÜV inspection is every 2 years and AU is included since last year. Costs are about 100€. O.k. this is completly off-topic, but i didn't have any problems in the past getting TÜV-aproval with the smart or any other car. They check brakes, suspension, lights, tires... everything about safty. They don't care about the optical condition of your body, a least you have huge rust holes in you car body. Well - it's a little overpriced, it only takes about 10-15min.Taxes for new cars are now based on CO2-emission. Older cars are calculated on motorsize and emission class. My cdi would be 133€/year.2 litre Sierra (worst case: Gas would be 20x25,36€ = 507€ = 710CAN$, Diesel: 20x37,58 € = 752€ = 1052CAN$)
