Should I make an offer on this Recteq 590 on an ebay local listing? $550, I could do a lower offer of $400?

It's drivable for me, should I put in a lower offer? This is one I have wanted and with it normally $900 this might be a better price?

I can take the legs off and put it in the back of an SUV?

Never bought anything off of an eBay local listing before.
