hello to everyone on the forum, my job entails a fair bit of offroad driving to get to work sites i have previously owned 3 discovery 300tdi and they have done a good job unfortunatly it has become difficult to get a good one mainly through rust issues.so i have been looking at colorados the head issues with the early engines are a bit of a concern and the d4d are mostly too expensive,however there are a few older ones around the £5000 mark so which do you think would be more reliable a high milage d4d with history or the 1kzte ,i would also be using the vehicle to tow a caravan.
