Everyday car with which you can often pull a trailer….

Hello! I’m looking for a new car. There is a Touran 1.9 TDI from 2009. It should be gone, another one. Actually I’m satisfied with the car, but now the turbocharger is gone. To the new car I make the following requirements: – trailer operation is a topic min 1 times a week, here it is mountainous, so he must be able to decelerate, I have a 1.3t trailer braked. – I want to be able to drive with the car on vacation, we are three have a dog – to work s 13 KM easy track without motorway – economy and quality would be good, so no car what is vulnerable – diesel or petrol? What do you think? Running power per year approx. 15,000 KM, I am a diesel friend, as it makes me much more fun (subjective) I look forward to your suggestions with advantages and disadvantages!
