Car 3 is a 750D Giulietta Spider. Alfa started the Giulietta line as model 750 and then in the early 60's siwtched the model numbers to 101. The last Spider sold in 1994 was an evolution of the 101 series, designated with 115. Back to this victim, there is no indication in the ad if this is a Veloce or Normale 750, Veloce's now command big enough bucks that you might be able to restore this fright pig and not lose your shirt.
Per the seller: "Prefer to sell the complete collection, will not break up. These cars are appreciating fast on the classic car market. Buy them all for the price of one restored example."
