I found an 85 GN for sale, the lady im trying to buy it from says it hasn't run since 2000, and needs a "modiguel" I assume she meant Module, maybe ignition? Wondering what I should look for as far as common rust spots, and common no start issues? Once I go look at it im going to check for spark/fuel if possible. She lives a decent haul away from me, but is asking 2500$ for it. Considering it but its a risk as i wont know the condition of the motor/trans
