Hi,
we have a 2019 V220 which seems fine after a year.
Apparently the sliding side doors have a plastic roller that disintegrates with use but not heard or experienced any other problems. The 220 has enough go and returns 30 round town and o er 40mpg on longer runs.
I guess the usual service, maintenance checks before buying.
The seat arrangement cannot be changed as the rails are built in for an 8 seater or 7 seater. I mention this as I considered buying either and just changing the seats to get what I wanted,
