Yesterday as I was getting my oil changed, my mechanic told me that because the late-model Mustangs are not "Full-Frame" bodies, any damage to the quarter panel is considered "Frame" damage, and due to this, I will take a significant hit on the trade-in value.
The book value is listed as around 7,500 on trade in. I currenly owe about 6,500 on the original loan.
Is this true? Is quarter panel damage on a 05-09 Mustang considered "Frame damage," and if so, how much will it devalue the car on the trade-in?
