the berlingo has a 3 seat option, but keep in mind that where the third seat would be you get a cubbyhole about big enough for a loaf of bread. So in three seat form your two passengers would need to be really, really good friends. Even transits aren’t particularly nice for three.
3 bikes without removing front wheel
is this really a concern? I’ve got a sprinter and an astra van. The sprinter I can toss the bikes in whole, just lean them against the side of the van, i don’t tie or strap them and they stay put while I’m driving. The astra I need to take a wheel of each one and do a bit of manoeuvring, maybe stick a blanket between them. But seeing as that only takes a minute at each end of the trip I always take the astra.
