Windshield will crack for sure, try putting some super glue or anything to seal the chip so air and moister can't get in.
Yea I hate to sell the 340 I should keep it.
My collector car insurance gives me one free windshield repair, so I just need to schedule them to come and do it. Spring is coming, so no hurry now, but it'll be fixed and heater reconnected before next winter!
