geting a savage 25 for almost nothing

[whitrzac]

I'm geting the savage in this pic for about $100, I am told that it has upgraded diffs, I'm not new to RC or nitro, but I'v never realy looked at geting a savage before.

what upgrades are recomended?
any parts that I should have on hand since I live an hour away from a hobby shop?
I was thinking about converting it to a savage x using this "canversion" any opinions?
