The glass still seems to be in place, but the rear windows are taped over. What's going on? Break ins? Heat making the glass shatter?
I also happen to remember to see one or more of the type of car lately. My estimate, rear window broken and temporarily fixed with tape as either a new window not on stock @the dealer or the owner not enough cash to pay for the repair.
Hold in place? Where do the owners think the glass is going? - I'll bet one rear window shattered for ? reason and the "word spread" to tape them babies up before yours shatters as well !!
