I was surprised how DIYable my Porsche is. I didn't buy it for that purpose but once I got into it, its all 13mm bolts like many other cars. It burns gas and air and uses oil. I thought it was supposed to be an exotic. When I have seen Ferarris dissected up close...same thing.
I'm sure special tools/expensive parts are involved but millionaire playboys that bought them new weren't likely to get grease under the nails or on their pastel blazers....
