I just bought a 1996 Taurus LX wagon about a month ago and took a road
trip Memorial Day weekend with a couple of friends.  It was someone
else's turn to drive and accidentally they put the gearshift into 2nd
gear instead of D and drove about 15 miles at 5000 rpm and the engine
overheated.  I did not notice until it was redlined (it was storming
so there was a lot of noise everywhere) and then we pulled over but
the damage was already done.  When I got it towed to the shop they
told me that I need a new engine on it since it had cracked due to
having been stressed too much.

My question here is whether it's worth it to replace the engine (about
$1000 + some shipping for an engine with 55k and $400 labor) or
whether to try to part it out.  I bought the car used (127k) for about
$2000.  I am wondering if anyone can tell me where I can try to sell
parts off of it (if there is even a market) or just take it to the
junkyard and accept the $100 for it.  My main question is whether the
investment would actually be worthwhile in the end.  I'm in college so
I'd prefer to fix if possible since a new(er) car would probably start
costing me around $3000 or so but I don't want to risk the $1400 and
then have a car that needs constant fixing.  Thanks.
