Being in the throes of a Europa renovation, though mine is a Twin Cam, I agree with most of the above.
I'd say the first thing to establish is that you really do have a complete car, and not 2 sets of components that both lack the same unobtainable bits (though I have discovered that not much is totally unobtainable). If all is there, bid what you can afford. Otherwise, assess what you have to source.
I don't agree 100% with dwkoski. I never have all the car in bits at once! For example, with the Europa, I removed the body, then the front suspension and steering. Then I overhauled that, rebushed wishbones, new bearings in hubs, etc, clean and paint and put in storage, ready for reassembly.
Then take some more off, overhaul, put aside, etc. until you get to bare chassis. Once you've done the chassis, assemble components again.
My way, you intersperse negative (disassembly) with positive (reassembly) and you don't have nearly as much to remember when you come to put it all back together again!
By the way, I'm now back to a rolling chassis with engine and transmission in place and just a few details before I put the body back on - starting end November last year. I am, though, retired so can spend a fair amount of time on the job.
Chacun a son gout!
