I think I understand now. The Berlingo Multispace has received a facelift for 2012, and new models coming onto the forecourts from April will have a changed appearance. Hence their (ex-)demo car was no longer completely representative of what they are selling.
Am I bothered? Not in the least. I like the look of my car, and I like the price even more. Furthermore, I didn’t have to wait 8-12 weeks to get my hands on it.
