Some say that the funniest jokes stem from reality and the reality is Ferrari's leak. I had my Testarossa engine completely overhauled and within a month it started leaking again. I have heard from some that if you drive them on a regular basis they don't leak as much.
I know about five people who also have older Ferrari's and all of them leak. I have heard that their newer cars are better, but I don't have any experience with them. One Ferrari is enough for me right now!
