I’ve got both, T5 converted camper and a Vivaro which is/was used for work.
VW has only got 30k miles on it and touch wood, nothing has malfunctioned so far, the Vivaro on the other hand has 60k on it and has so far had 3 ECU’s, 1 turbo, 1 intercooler, 1 exhaust, 4 tyres and various plastic parts as they have fallen off! ECU’s done under warranty as they happened in the 1st year, turbo went bang 2 months ago and took intercooler with it, £1500 bill.
VW is an ’08 130bhp LWB and was bought 1 year old with 15k on it for £11,000 although research would tell me this was cheap compared to the prices they fetch now…
Vauxhall was £9995+ Vat brand new.
The VW is a much nicer place to be and a much nicer drive. for my money I’d have another VW in a shot, I’d never buy another Vivaro.
