Ignition module at about 70k.
This is a super durable vehicle. The 1980 is considered the best year since it has more factory rust protection than any other year. The engine has plenty of power, adequate for towing trailers less than 4,000 lbs. This Scout has factory air and a factory towing package. The engine is commercial quality, 6 bolt mains, forged crank, it weighs over 600 lbs.
I have a Jeep also and it is fun, but it does not even come close to the quality and engineering of the Scout. Check Ebay, good Scout II's go for 5 to 12k.
An awesome classic 4x4, buy a good one, drive it like crazy, and make money when you sell it.
Good luck finding one that hasn't rusted to pieces. If the 1980's had better rustproofing, the earlier models must have had none.
