Tbh i'm more worried when a diesel has low mileage,after all the main reason for owning 1 is when you do high miles & if you don't theres no point owning 1,low mileage 1's usually suffer from sticky turbo's etc
A year ago pd150's were going for 4.5k-5k now you can pick them up for 2.5k upward,they have come right down in price
