It seems like it’s personal preference really. I’m a big fan of Renault Master, I’m down to the last of our Sprinters.
I sold a Master last year, 55 plate, body was mint apart from a small ding, 365,000 miles on the clock and the engine was still sweet, original gearbox.
I usually expect to get around 300k out of them at least. As Dave says, servicing is the key, we service around 12,000 miles as opposed to the 18,000 recommendation. Im not getting more miles out of a Sprinter tbh and the last one I sold on a 57 plate was in shocking condition bodywise.
My other point is that you are spending a lot of time in the motor, factor your comfort in as well.
