I'm certainly no expert, but I've got a 92 too, so let's see what we can do.

First question: How many miles do you have on it? Are you the original owner?

There's 135,000 miles and I am the second owner

Well, I was attempting to elicit questions so as to pique the interest of the other old hands who might generously look upon your plight and lend a hand.

Anyone?
