I think you'd get more from a private person, go to kbb.com to price it, and then deduct how much the repair would cost. Best place to sell a car is craigslist.com. A private person that can fix cars would be more interested.
Ford had overheating problems with the Contour, think it had something to do with the head gaskets, but if it's okay at 94K, guess that one didn't have the problem.
go to autos zone / advance auto etc! and buy a book it will tell you everthing about your car god bless good luck
The most common problem is vacuum leak on the intake.
You might want to take that truck to a local dealer there was a recall for the head gaskets to be replaced free of charge.(if it is a six cylinder) the recall was x01. Then you could get your vacuum leak fixed for free. U may have got mud in the bearing on the front of the alternator or idler pulleys as well.
hoses are normal. par.
t-stat giggle valve up top and a bled system with the heater temp on full.
head gaskets can be bad w/o cross contamination of fluids. not uncommon at all. can still cause over heating and further damage. check w/your mechanic to find out why they think it's a bad gasket. heed there advice.
i see nothing out of the order with the mechanics at this point. don't know enough about the symptoms to support any other conclusion.
Have to laugh at Betty's answer, almost all competing GM products have Mexican made engines, Toyota's are largely U.S. built.
To answer your question though, your husband will probably wish he just put in a few extra hours at his real job that he already knows how to do, as opposed to trying to jump off the deep end into a fairly difficult job even for an experienced mechanic.
The Camry head gasket job will be complicated by the necessity to do the timing belt at the same time. Not fun, especially if it's a V6.
