The value of a 1978 Mercedes Benz 280SLC in Australia can vary greatly depending on its specific condition, mileage, and any custom modifications. Original and well-maintained examples with low mileage can command higher values compared to modified vehicles.

Original 1978 Mercedes Benz 280SLC:

In pristine condition and with low mileage (80,000 kilometers), an original 1978 Mercedes Benz 280SLC could be valued anywhere between AUD$35,000 to AUD$55,000.

Custom 1978 Mercedes Benz 280SLC:

The value of a custom 1978 Mercedes Benz 280SLC heavily depends on the extent and quality of the modifications. Well-executed modifications that complement the car's classic character and enhance its performance could potentially increase its value. If the modifications are not professionally done or negatively affect the car's originality, they might actually decrease its value. Therefore, it's difficult to provide a specific estimate without inspecting the vehicle itself and understanding the nature of the modifications.

Please note that these values are just rough estimates and can vary significantly based on various factors such as location, market conditions, and individual buyer preferences. To obtain the most accurate valuation, it's advisable to consult with a reputable automotive appraiser or car enthusiast who is knowledgeable about classic Mercedes-Benz vehicles in your region.
