My ex father in law had a vivaro. He bought it with just 2000 miles on the clock. Had injector problems, dpf issues, scyncro go, an electrical fault with the ecu that kept making the van stall. All issue were fixed under warranty,... wouldnt touch one with a barge pole though.
Im happy with my connect. Reliable, smart, and inexpensive to run. Id buy another no worries.
