Help me choose! (Updated)

A celebratory high-end 1:18 model.

Why? Well because today I took my final final exam...for the rest of my life...and tomorrow I defend my Masters Thesis. I am going to convince my wife that I deserve a treat :D Plus my birthday is soon and just got our tax return back. Basically I am coming up with as many excuses as I can haha.

Here are my choices:

(UPDATED: It’s now down to the F40LM, Alfa 33 Stradale, and Martini 917, I plan on owning all of them some day haha)

Kyosho F40 LM (thanks to TE71 for getting me hooked on this one)

AutoArt Alfa Romeo Tipo 33 Stradale

AutoArt Porsche 917LH #21

So...let me know which one I should get!
