Looks like a nice job.
It is amazing what you can do with such a relatively small vehicle.
If I was ever going to do similar I would buy a brand new Ambro Bootjump to be fair.
Silver Berlingo Multispace 1.4i Forte
That conversion's much better than a bootjump if you want more of a dedicated camper. The bed's a bit narrower, but you've got an oven, hob, sink, lights, mains connection, roller blinds and no doubt lots of other goodies.
It also looks like it's completely unused. It's got to be a distress sale, as it's a bargain price - it's a grand more than a bootjump, and you get lots more, plus the van itself. Presumably a lower offer would be considered too.
Even if the van itself is knacked (unlikely - it looks immaculate), you could still transfer everything to another donor old-shape Berlingo Multispace and it would still probably be worth the money for the camper parts alone.
Looks like a good buy.......but be aware that for two people the bed will be narrow! Conversions with a side cooker/sink all have narrow beds. Ideal for one person though.
I brought an Amdro Boot Jump because of its huge bed, the full width of the Berlingo.
