I've had a Vivaro with over 100k on it without problems. I've currently got a 80k+ Transit custom (19 plate) that broke down after 3000 miles (injectors). It's been fine since. Workmate had his injectors go twice. Had 3 Vauxhall cars, Astra GTE, Cavaliar and Vectra. All good cars that served me reasonably well. I don't think any mainstream make is really better than any other. A lot is down to how you treat them.
