As some of you know I recently aquired a 67 326HO car with 57000 miles. its just an unbelievably gorgeous car that had 1 repaint 25 years ago and it looks like it was done last week. heres my dillema. the undercarriage is unrestored, no rot or rust through but some mile surface rust (patena, normal wear and tear, etc... I did remove the original style exhaust that was installed in 1985 and put some nice custom made duals on it so you could hear it run! so do I " restore" the undercarriage with a simple scuff and spray or just leave it be for originality??
