We have had our 4.4TDV8 since 2013 (my how time flies).
I always find with forums when you search you only find the problems
but that’s the nature of a forum to help others fix things.
Our personal experience is very good, it has always been serviced well and I would say has probably not cost anymore overall than any other brand. A few things that would not be considered normal for the age, but those that seem common to the model.
We don’t do huge mileage at the moment, but have done and it has been out of the country on many occasions and back under its own power
Towing for many of those miles too. You never hear of the miles some put in with no problems.
Keep looking for a good one they are out there, save a bit more while your looking. As has already been said you know what to steer clear of.
Happy hunting
