Hi I’m looking at a 300tdi it’s very clean from what I can see. I’m only getting into it. People keep telling me don’t get one they always go wrong it’s a waste. I jjst want some help as I’m so torn between getting one and just not bothering. I know I will have a laugh with it. I know every car truck whatever they all go wrong at some point. Just wondering like how bad are they ? I probably will go off road but I’m not going to go silly. Just not sure like I’m worried it’s going to cost an absolute fortune. Hope you can give me a good in site to it all ?
