1978-79 Suzuki sp370 value
 

This is a true barn storage. My Sister purchased this bike in 1985 and found it too heavy for her families liking. They have had it in the barn area in storage. My research states the model was only made for 2 years. Is there any value or interest in this model. Thank you in advance for your responses.

Here is how it looks since being parked in the early 80’s.
