With your updated info (no winters, always stored inside and covered, car still very nice), and assuming there are no docs, I will guess $32 - $37K. If you truly believe that you're going to keep it this time (as opposed to buying it and then flipping it as soon as the old 'sentimentality' wears thin) then you might add on another $5 - $8K. As Sam has indicated, the fact that it's a true two owner car, you bought it new and have known the car it's entire lifetime is pretty much priceless
