I procrastinated on a ‘67 Mustang coupe last fall.
The owner had put it under a tarp and condensation had its way with it. The interior was really bad - but he had a brand new complete interior kit for it. 351W and 4-spd.
The doors were rusted shut - I was afraid that I would going to destroy the doors trying to open it. I knew that I would have to remove the fenders and pull the doors, then pull and replace the hinges. I was very reluctant to start in on another rustbucket - especially for that price.
He was asking $4k. I offered $2k and he gave me the pained expression before shaking his head no.
I put out a couple of casual feelers but he wasn’t budging. Well, I found out this week that he sold it. He got $1800 for it.
Rats.
The first thing to check on Mustangs is the torque boxes on the sub frame under the area of the driver's feet, if they are rusted out there will be serious rust problems elswhere.
When you go to look at a car like you are looking for always go prepared to crawl around under the car, and search for rusted areas.
