A Speedster 356 is a selfish lifestyle choice. Some wife's tolerate them but most don't love them. There are for people who dream a lot and or like to tinker. Pound for pound there is not much better in the Cool 
Department. The lines are endlessly Euro's version art deco and beauty. They are raw, than can be fast, and semi comfortable. They are not cheap anymore & most are not very weather tolerant. They are very seasonal too. Depending on where you live it may only be a 3-5 month toy. I have had two, one from the entry level to one on the very high end. 12 years combined. I just sold one because there is a lot going on in my life. I know I will miss it some day.
I like muscle cars but fell out of love once I realized (circa 1980's) that a 130hp Euro car or even a Mazda RX7 could dance circles around an overweight brut muscle car on a back road. It depends on where you get your kicks. They are both great but they are so very very different.
