Another satisfied Legendary customer here. My first purchase from them was over 10 years ago. I have pitted one vendors best price quote against the other to save a coin but wouldn't buy from anyone else.
The installation will turn out as good as you want it to.
I've seen a few cars on ebay with "new seat covers" in the description. Their pictures showed several wrinkles. Possible reasons.. Not Legondary products, installer didn't refurbish or replace the filling be it foam or batting.
Skins are supposed to fit tight ! If installation isn't labor intense you're not doing it right.
