Yup - VERY rare. Only 963 1958 Edsel 'Roundup' 2-door station wagons were built. And there were NO 2-door Edsel wagons in the '59 or '60 model years. One thing you might want to double-check, is make sure it's registered (and built) as a true '58 Edsel. It wouldn't be all that difficult to 'build' one from a '58 Edsel front clip and a '57 Ford 2-door wagon. LOVE the model name - 'Roundup'.
Easier to find and restore an actual Edsel wagon than to find the parts to make one. For instance, those chrome spears are for the 2-door only. Stainless steel is what they are, and to my knowledge, not reproduced. Dash can be installed into a '58 Ford 2-door as can the tailgate and liftgate. But those spears are unique to this model only.
