When a “Small Fix” Becomes a Big Problem

Sometimes what looks like a minor issue—such as a check engine light—can hide serious mechanical damage. If:

• Repair costs exceed the car’s value

• Problems keep recurring

• The car frequently breaks down…it may no longer be worth fixing.

• Non-running

• Too expensive to repair

• Old, damaged, or written off
