No. If you have a choice, never buy a used vehicle that you know has overheated. You can never know how badly it overheated and for how long, and it can do immensely terrible things to the engine. Things that might not even be apparent for several thousand miles, but when they crop up are killers.
You still have your $, count yourself lucky that you missed this one.
$1k will buy you an ugly but reliable vehicle that's much more robust. Things like Police crown vics, Lesabres and similar GM 3800-powered vehicles, etc. The simpler the better really at that price. And above all : value a smooth good running vehicle over style. All too often I see someone say 'wow, look at this '99 Eclipse Turbo, only $1,200!, all that's wrong is the head gasket is leaking! what a DEAL!', and boom : they're stranded almost immediately by a gigantic money pit that they have to turn around and part out or scrap, or it gets towed and it's more expensive to get out out of the pound than it's worth.
