The hood and trunk rust doesn't look significant. I can't see the rocker panels or areas at the back of the wheel wells well in the pic...the area in back of the driver's side front wheel well looks suspicious.
Of course, it depends on whether you want to spiff it up or just drive it.
If you buy it, you must of course only drive it wearing a black suit, white shirt and black tie, black stingy brim fedora, and sunglasses.
