This is essentially a seventh gen Daihatsu Hijet (which entered production in 1986) built by Piaggio in Italy. The most notable change that the Italians made to this Daihatsu was the intrudaction of Italian made Diesel engines, including a 1.2l inline-2 Diesel. I see quite a few of these Piaggios around town (although in the truck variant, not vans) because they're used by the local municipal landscaping services.
