Ask for all the maintenance records. Make sure the timing chain was replaced. If not, it will have to be replaced soon. Electronic gremlins are bound to give you more fits than anything else. Corroded or loose connectors and bad solder joints on circuit boards are a fact of life.

Make sure the defroster vent isn't always on. That would indicate a bad vacuum pod or control valve. Make sure the cabin air stays at the set temperature and doesn't fluctuate wildly

Check if there's any flare during the 2-3 shift.

These old cars make sense if you are somewhat handy. Repairs can end up costing you dearly otherwise.
