Time travel, Xander rescues Spike

I'm looking for a fic where the Scoobies go back in time. I believe Buffy is first and then other characters start to show up, like suddenly they are their future self. I think Buffy makes an apartment over her mom's gallery. At one point Drusilla takes Spike and when Xander becomes his future self he goes down to rescue Spike from her in South America with a van and maybe someone else?

Anyone know this one?

That's Second Chance by Jackofspikes. You can also find it over at Elysian Fields.

Unfortunately this story is WIP - with last update way back in 2012.

I'm bummed it's a WIP, but that's it! Thanks!!
