1999 Dodge Intrepid Engine Blew

My engine blew about 7 years ago, I took the car into be looked at and was told to fix the following: timing chain and damage the broken chain had caused as well as the engine.

This car has been parked outside in Michigan weather for approximately 5 years. What extra damage may the weather have possibly caused this vehicle?

Approximately how much do you estimate these repairs being?

Thank yoU!
