Although replacement of the windshield may potentially cost substantially more than repair work, there are times when this is your only choice for a safe trip. The cost of replacing a windshield would significantly depend on the type of car you have and the characteristics found on your windshield. For economy-type cars, luxury vehicles that have windshields with multiple features usually cost more than regular windshields.
