I had a 2002 vivaro and the gearbox went under warranty which was free swap just bit of hassle loosing your van for couple of weeks, after 3 years 60K miles on it with no bother, Bought a 2005 transit after this which is uncomfortable, noisy and I broke down many times although it never cost me anything to fix it, put 30K on this thing.
Then I got a 2005 transporter 2.5 tdi 130 lwb with no warranty as there expensive so got an older one just out of. There a good van and go like the clappers, but after 4 years and 60K miles things started going wrong, I spent ÂŁ 3500K on top end rebuild as the cam snapped, then i snapped a drive shaft, then the other side snapped, then the altenator went, so I got rid last year and bought a bran new vivaro Lwb 115 61 plate sportive.
This is my second vivaro and they drive really well and the sportive looks smart. I got three years warranty. ÂŁ12500 plus vat off the net, delivered to my door. you cant get a smarter van for any less.
