I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
The diagnostic costs a hundred plus and then there's more for the cap to the fuel tank. The problem is it could have been something serious and I wouldn't have known. It's worth the money to know that my car will not spontaneously explode!
I still ill got out of this with less than two hundred in damage which is good! I'll have my car back tonight and won't have to worry tomorrow. Yay!
