Hmm..I remember posting a response here, I guess it got lost in the crash...
I got an advanced reader copy from a friend who owns a bookstore (I found a few typos/misspellings

) And its a good read. Its more about their "adventure" than VO, although that does play a big part in their trip.
The gist is, the guy gets a TD and has a greasecar kit put in and convinces his wife to let him drive from vermont to california. She agrees when he says he;ll bring someone along who has a clue about car mechanics. I guess since he writes for a living, he's not terribly handy under the hood. Anyway you can see the fun plot build from there
Its fun reading about two people and their trials and tribulations associated with finding oil and keeping the old TD running. It would be worth it to pick up for a plane ride if you're interested in old mercedes and VO.
