I dis'd the Escaine when I first saw it. Lexus' line about reducing driver slip versus full leather sounded bogus to me - put better side bolsters on the seats!
But I got over it. In fact, since I expect the Escaine to wear very well, I decided I actually like it, perhaps better than my wife's full leather RX seats. It is cool in the summer and likely warm in the winter (or as close as we get to winter in So. Cal.!). And it does keep yer butt from sliding around...
Yeah, Lexus put the Escaine (fake suede) on the IS seats but I do like them alot. Definitely stays cooler than leather and won't crack like leather does. How it does wear over the years is of course still up in the air but the Escaine does work nicely and looks good, too.
I had cloth on my old MR2. Remember those bright blue stock seats that matched the bright/light blue paint? They wore extremely well and were easy to keep clean. On that basis I expect the Escaine to do the same.
