Check out the Spyder club website if you want one of these, people often selling off unfinished projects or complete cars in a hurry for a fraction of what they cost to build.
Wait, that sounds kind of familiar...

Jake Raby (of RAT) hangs out there, he just sold his own personal 550 on Ebay (it was in the classified on Spyderclub):

It closed at $27,500.
I think new turnkey 550's from Beck, Vintage or Thunder Ranch were pushing $30,000 a couple of years ago - and you could easily get way over that with a non-basic motor or all the spendy authentic retro details.
Power-to-weight in one of those things is a real attention-getter with a tweaked 4-banger - and some people are building them with Subaru motors and modern brakes and suspension geometry too.
Still got absolutely no crash protection and a body shape that tends to fly over 125 MPH though...
Sure would be a fun toy. I love the quote from one of the original Beck road tests, which I think went something like "it's so tail-happy you'll get it wagging in the parking lot, but it always goes where the heavy wheel is pointing"..
