That Milano is interesting. It has the Campagnolo magnesium wheels of a GTV6!
The blue two-door car is not a GTV6 (notice lack of "hump" for the engine) but an Alfetta GT/Sprint Veloce, with the typical Alfa Romeo 4-cylinder. Probably too far gone - those used to rust as if there were no tomorrow.
If the grille and bonnet have not been changed that Dino Coupé has the alloy 2.0 V6, and a leaf-sprung live axle at the rear. Which makes is slightly less interesting, technically - the 2.4s had IRS, shared with the 130 and, as far as I know, the 131 Abarth Rally.
Incidentally, both the Alfetta GT/GTV and the Dino Coupé were designed by Giugiaro (the Fiat while at Bertone, the Alfa when he had already set up ItalDesign). Unfortunately Alfa Romeo messed with his initial designs somewhat and he disavowed it.
Regarding the Beta Spider... good luck to that man! These converted chez Zagato (Pininfarina did the design). From what I've read in this particular case their workmanship was pretty rough, done clearly on the cheap.
Having said that, I love those cars. I felt tempted to import a cheap one from the US years ago, but it was a west coast car and got cold feet.
