I grew up with the Kamm tail cars (and later the ugly rubber duck tails), but always preferred the Roundtail cars as the perfect expression of that body. You're right, you used to be able to buy them relatively cheap (although the Alfas were always just a bit more than the Fiats, MGs, Triumphs, Datsuns, etc), but now they're getting pricey. One just sold on BaT for $97K! Though you can still find ok runners in the $20K's.
The owner of this white '67 wanted $30K, too rich for my blood. But I had fun helping to diagnose a carb leak and rotor phasing issue with it. Old Italian cars are like boats, most fun when playing with somebody else's. Besides, I've got a Porsche 951 that more than keeps me on my toes.
