We are having our Wilsonart flooring extended forward from the kitchen to the front in late July. Will let you know how it goes.
Installer doesn't anticipate any problem re: the driver's side slide. We'll leave the carpet covering the slide floor as it. One issue might be matching the existing and new product. We have the Wilsonart product number and are crossing our fingers that the lots match close enough. Other issue is whether the existing "wood" can be pried up enough to get out the boards necessary to extend the floor without use of a transition strip. Unfortunately, WRV glues the floor down (at least on our model) instead of using a floating floor.
If the new product matches the old and the boards can't be pried up, will use a low profile, built to match transition strip. Worst case scenario, we tear up entire wood floor, fill/fix damage to subfloor, and replace with floating new floor. At least double the cost, but has advantages in eliminating some existing tiny gaps (apparently caused by installing boards with greater than 6" overlap) and one small area where flooring has lifted slightly.
