AKA the Blue Van, the Antique Express parks outside your zoo and allows you to buy special pieces that you missed. Decorations from a winter campaign three years ago? Here they are! NPCs you missed? Yep! Animals? No, there are never animals. It costs 750,000 or 30 diamonds. Never spend diamonds if you can spend ZD! Remember, diamonds are real money! It puts up a new trade every 45 minutes. Don't, like, camp out there, it all comes around again.
Should I get it?
No, not really, unless you're a total MFZ addict and you just have to have that, like, mighty rock from five years ago. Even more often, when it's winter campaign time you get previous years' winter campaign stuff. (And summer, Valentine's Day, etc.) There's some cool stuff there but it's all window dressing, right? You're here for animals. This will not get you animals. I mean, I bought it anyway.
Some weird old stuff you might want
Aztec pyramid!
Lighthouse!
"Mighty Rock"!
The Eiffel Tower, for some fuckin' reason!
