Old restoration that was stored poorly.
Anything can get covered in dust even if it only sits for six months. The owner is no doubt so sure of the cars condition and value that he doesn't think he even needs to clean it up for better looking pictures. It may be a really good car but the pictures don't really reflect this.
And if someome were to buy any of my old clunkers for 25 large I'll throw in lifetime car washes....![]()
He forgot the "owned by a little old lady that only drove it to church and back" line.
