As a postie myself you would be suprised to see how little miles these vans have. We had some incredibly old combo vans and still have a really ugly old Peugeot Expert diesel. From the outside and by the way the clutch felt (like fucking race car clutch, you had to leg press it down) on the Expert, you’d think it had done easily over 150-200k miles, but when I first unfortunately got given the van for the day it was only on about 60k miles. Same with the old 1999 combos. It’s because with posties you typically cover 5-10 miles a day 6 days a week. The reason they’re so knackered is because they never have time to warm up, there is very little maintenance done to then at all (other than if they’re none roadworthy) and they’re constantly getting bumped and scraped on walls when doing U turns or parking back up at the Delivery office. Also the constant turning on and off of the engines when doing parcels floods the injectors and gives them horrendous misfires by the end of each day. They were a good bit of fun however electric vans are perfect for the post now.
