Thanks for the reply. My wife has WT mats in her car and I noticed the limitation regarding the door side lip (or, the lack thereof). For the $10 worth of material that goes into a set, you would think that a few cents more for a door side lip would be a really good value and make sense, especially for how much that you pay for a set. But, it seems like every set from every mfg is made that way, so, maybe it's a manufacturing limitation. But, I find that hard to believe since they are probably just vacuum-formed in a press.
