Have a very good test drive, looking/feeling for any kind of driveline klunk/klonk/knock or shudder – any sign, walk away. Also check the warranty history, as there are good vans and not so good vans.
My T5 is great, but in 60,000miles has had under warranty:
turbo
sliding door lock
exhaust pressure sensor
3 x dual mass flywheels (at least one was faulty)
both driveshafts
2 x clutch (the 2nd replaced after the dealer damaged the input shaft oil seal)
rear number plate lamps (first MOT under warranty!)
As I contributed to the last clutch/DMF replacement (total cost £1500), I get a 2 year warranty on those parts – might be worth it!
There are vans out there that have never had anything go wrong, but you need to go in with eyes wide open and don’t be swayed by supply issues or shiny paint.
Also, check out London sellers – next years Low Emission rules might mean that older (Euro 3) vans are going cheap – from what I have been told van drivers inside the M25 might need to be Euro4 (DPF) to evade the Low Emission tax (or something like that – worth looking into)
Also, if your van is a 6 speed (check it is, not just a 6 speed gearknob), then it is a 2.5, and either a 130PS (likely) or 174PS (not likely). 174’s command a real premium, so the seller will be using this.
I love my van – had it 2 years, and it’s a decent camper conversion, but if I hadn’t spent so much time on the insides, I might have swapped for another more reliable van.
