I'm looking at another MB, much to my wife's chagrin, and I wanted to see what the value was as listed on a used car resource.
The Kelly Blue Book does not list anything this old (1982), Edmunds tells me it's worth about $1200 and NADA lets me access a value only on the Classic tab. There NADA tells me it's worth over $10,000

, but it also list my SD at about the same value

.
With these resources, it's tough to determine the real fair market value.
