Good idea. Just sent a note to Weathertech. Ordered from: www.kbcarstuff.com
I was in the car this morning (cool, rainy day). Some of the gaps seem to have noticeably shrunken . Makes me wonder if there is a thermal expansion thing going on - I noticed the larger gaps/buckles on a warm/hot day.
The buckling may be the simply be the result of the lengthwise expansion of the liner. Hmm.
We shall see if WT replies.
