I'm running the full fat extended warranty, and have already had a door lock & labour paid for since I took it out. So I'm pretty much breaking even on a £300 bill I would have paid for. And 6 months to go. Nearly in the black
Plus I use a very good dealer & have their 3 year service plan.
Not sure if I'd go for year 4 to 5. Depends on cost.
But remember, unlike the manufacturer 3 year warranty, the terms of the extended warranty are that you
must have the vehicle VW Dealer serviced. The warranty is underwritten so is not a direct VW product. It makes sense if you already have a full VW service history & a fixed price service plan, but if you don't, I'd look at Warranty Direct as well.
