Oh no! I understand what a big problem it should be for you! Where I live in the middle of nowhere, there is no other possibility than having a car!

I agree with Barbara that trying to find another second hand car would be the best. You never know if after changing the engine it will pass the control. And I agree, don't go for a French or German one if you don't buy them new. They are fine until they are not too old and that you don't have to change something...
