Thanks for the feedback. We live out in Northern CA, we can't blame kids or pets since we have none.
I have my hardtop stored this way for the last 4 years and never had a problem. My husband sweared that he didn't hit it, even when he could probably hit it when he is lifting beers out from the front trunk. i will give me the benefit of the doubt since he is usually very careful, with the exception when he is drunk. hehe. We did have a cool spell 2 weeks ago, we got to below freezing during the night, but I think the glass should be able to handle the temp. So i guess i have to treat it as things comes in 3s. For the week, I did a 40K maintenance, front breaks replacement and now have to replace the glass, costing me lots of $$$.....sign!
I will let you know how much it cost once I get an estimate tomorrow.
