The question to you is: We measured the limit for insurance and/or tax at the engine capacity, or at the PS number. The question is whether a 93’er 1.3 liter 75 hp Colt is as expensive as a 93’er 1.2 liter 45 hp Opel Corsa? Or whether the 93’er Corsa 1.2 L 45 hp is as expensive in the insurance and/or the tax as a 93’er 1.6 L 113PS Colt? The Corsa is only a comparison value. Only the limit is wanted from when the costs of insurance and/or taxes increase and what the measurements are made (hubraum, PS,…?). Hopefully someone has a clue. 😉
