There are so many to choose from. The Alfa Romeo Giulia 1600 Tubolare Zagato (TZ) Coupe by Pininfarina, the Alfa 33 Stradale and the Jaguar XJ13 are just the first three I thought of this morning. What are your picks for the most beautiful cars in existence? Note: I know we have gone through this in some earlier posts but they are always fun and seem to show me something new. Obscure choices are most welcome.
