Am I a masochist? I'm considering either a VW GTI, or an Alfa Giulia. Talk me into it or out of it

My kids are older, and I no longer need to own a minivan. My older son's lacrosse stick fits in a sedan trunk with a passthrough so I don't need a large car. I have a third car for when a car is in the shop or we have visitors, or I'm going into DC, and don't want to worry about getting my car scratched up.

I don't want anything large. I know Alfas have a reputation for being unreliable, but they are damn sexy. I also love the look of the GTI. I don't want to get something super fast since I don't want to get more speeding tickets, and I want something fun.

I've read reviews that say that either car will bankrupt me and steal my wife away. I'm looking at models that are two or three years old since that way someone else takes the initial depreciation hit.
