Surprisingly the Euro Buzz is not doing that well in Europe based on the Smith and Sniff Podcast I listen to regularly. They mentioned UK dealers had leftover units to push at the end of last year which was a surprise to them considering how much fanfare the vehicle got when it was first announced.
I've sat inside and played around with both the Euro and US-spec Buzz at this point. It's a nice boxy vehicle with a lot of retro-modern flair, but it's not that interesting of a vehicle after its novelty wears off. There are a lot of harder plastics inside and the cabin is a bit small compared to the typical minivans we get here. My least favorite thing is that tiny window in the second row - the opening mechanism is cool but I wish it didn't look like an afterthought.
