Wow that is really strange...do you think that maybe you parked too close to the garage door and the arm of the door came down onto the glass as you walked in the house??
That's possible. I'm sure it's the thermal properties of one not mingling with the other very well in any case. :beer:arbs said:we used to have a mini soft top (with glass in the hood) and it was a relatively common problem, i think its to do with different layers in the glass having different thermal properties and as one expands/shrinks it does so at a different rate to the one next to it - hence SMASH!
